Scientific journal, Abstract

Evaporation or freezing of water-rich fluids with dilute concentrations of dissolved salts can produce brines, as observed in closed basins on Earth¹ and detected by remote sensing on icy bodies in the outer Solar System^2,3. The mineralogical evolution of these brines is well understood in regard to terrestrial environments⁴, but poorly constrained for extraterrestrial systems owing to a lack of direct sampling. Here we report the occurrence of salt minerals in samples of the asteroid (101955) Bennu returned by the OSIRIS-REx mission⁵. These include sodium-bearing phosphates and sodium-rich carbonates, sulfates, chlorides and fluorides formed during evaporation of a late-stage brine that existed early in the history of Bennu’s parent body. Discovery of diverse salts would not be possible without mission sample return and careful curation and storage, because these decompose with prolonged exposure to Earth’s atmosphere. Similar brines probably still occur in the interior of icy bodies Ceres and Enceladus, as indicated by spectra or measurement of sodium carbonate on the surface or in plumes^2,3.

Scientific journal, Abstract

Apatite is present as an accessory phase in many meteorites and is often formed as a secondary product of aqueous alteration. Its propensity to incorporate rare earth elements (REE) results in apatite usually being the main REE‐bearing phase in hydrously altered meteorites. Asteroid Ryugu is thought to have experienced pervasive aqueous alteration and material collected from the surface of Ryugu is expected to provide insight into asteroidal aqueous alteration processes without influence by terrestrial weathering. Morphologies and mineral associations of apatite grains from five rock fragments collected from the asteroid Ryugu by the Hayabusa2 spacecraft were examined and their REE concentrations were measured by synchrotron X‐ray fluorescence (SXRF) spectroscopy. The main minerals associated with apatite are dolomite, magnetite, and pyrrhotite. Grain boundary corrosion of the interfaces between apatite assemblages and the surrounding matrix suggest that paragenetic formation on the asteroid was followed by a later episode of hydrous alteration. Light REE (LREE) concentration levels recorded at 20–150 times those of bulk CI levels together with a steady increase from LREE toward enrichment of medium REE (MREE, up to Er) at 50–400 times bulk CI levels may suggest postgenetic removal of LREE from Ryugu apatite grains by late‐stage circulation of a hydrothermal fluid.

Scientific journal, Abstract

In order to gain insights on the conditions of aqueous alteration on asteroid Ryugu and the origin of water in the outer solar system, we developed the measurement of water content in magnetite at the micrometer scale by secondary ion mass spectrometry (NanoSIMS) and determined the H and Si content of coarse‐grained euhedral magnetite grains (polyhedral magnetite) and coarse‐grained fibrous (spherulitic) magnetite from the Ryugu polished section A0058‐C1001. The hydrogen content in magnetite ranges between ~900 and ~3300 wt ppm equivalent water and is correlated with the Si content. Polyhedral magnetite has low and homogenous silicon and water content, whereas fibrous magnetite shows correlated Si and water excesses. These excesses can be explained by the presence of hydrous Si‐rich amorphous nanoinclusions trapped during the precipitation of fibrous magnetite away from equilibrium and testify that fibrous magnetite formed from a hydrous gel with possibly more than 20 wt% water. An attempt to determine the water content in sub‐μm framboids indicates that additional calibration and contamination issues must be addressed before a safe conclusion can be drawn, but hints at elevated water content as well. The high water content in fibrous magnetite, expected to be among the first minerals to crystallize at low water–rock ratio, points to the control of water content by local conditions of magnetite precipitation rather than large‐scale alteration conditions. Systematic lithological variations associated with water‐rich and water‐poor magnetite suggest that the global context of alteration may be better understood if local water concentrations are compared with millimeter‐scale distribution of the various morphologies of magnetite. Finally, the high water content in the magnetite precursor gel indicates that the initial O isotopic composition in alteration water must not have been very different from that of the earliest magnetite crystals.

Scientific journal, Abstract

Transmission electron microscopy analyses of Hayabusa2 samples show that Ryugu organic matter exhibits a range of morphologies, elemental compositions, and carbon functional chemistries consistent with those of carbonaceous chondrites that have experienced low‐temperature aqueous alteration. Both nanoglobules and diffuse organic matter are abundant. Non‐globular organic particles are also present, and including some that contain nanodiamond clusters. Diffuse organic matter is finely distributed in and around phyllosilicates, forms coatings on other minerals, and is also preserved in vesicles in secondary minerals such as carbonate and pyrrhotite. The average elemental compositions determined by energy‐dispersive spectroscopy of extracted, demineralized insoluble organic matter samples A0107 and C0106 are C₁₀₀N₃O₉S₁ and C₁₀₀N₃O₇S₁, respectively, with the difference in O/C slightly outside the difference in the standard error of the mean. The functional chemistry of the nanoglobules varies from mostly aromatic C=C to mixtures of aromatic C=C, ketone C=O, aliphatic (CH_n), and carboxyl (COOH) groups. Diffuse organic matter associated with phyllosilicates has variable aromatic C, ketone and carboxyl groups, and some localized aliphatics, but is dominated by molecular carbonate (CO₃) absorption, comparable to prior observations of clay‐bound organic matter in CI meteorites.

Scientific journal, The Hayabusa2 spacecraft investigated the C-type (carbonaceous) asteroid (162173) Ryugu. The mission performed two landing operations to collect samples of surface and subsurface material, the latter exposed by an artificial impact. We present images of the second touchdown site, finding that ejecta from the impact crater was present at the sample location. Surface pebbles at both landing sites show morphological variations ranging from rugged to smooth, similar to Ryugu’s boulders, and shapes from quasi-spherical to flattened. The samples were returned to Earth on 6 December 2020. We describe the morphology of >5 grams of returned pebbles and sand. Their diverse color, shape, and structure are consistent with the observed materials of Ryugu; we conclude that they are a representative sample of the asteroid....

A dual origin for water in carbonaceous asteroids revealed by CM chondrites
Laurette Piani, Hisayoshi Yurimoto, Laurent Remusat
低温科学, 78, Feb. 2018, [Peer-reviewed]
Carbonaceous asteroids represent the principal source of water in the inner

Solar System and might correspond to the main contributors for the delivery of

water to Earth. Hydrogen isotopes in water-bearing primitive meteorites, e.g.

carbonaceous chondrites, constitute a unique tool for deciphering the sources

of water reservoirs at the time of asteroid formation. However, fine-scale

isotopic measurements are required to unravel the effects of parent body

processes on the pre-accretion isotopic distributions. Here we report in situ

micrometer-scale analyses of hydrogen isotopes in six CM-type carbonaceous

chondrites revealing a dominant deuterium-poor water component ({\delta}D =

-350 +/- 40 permil) mixed with deuterium-rich organic matter. We suggest that

this D-poor water corresponds to a ubiquitous water reservoir in the inner

protoplanetary disk. A deuterium-rich water signature has been preserved in the

least altered part of the Paris chondrite ({\delta}DParis > -69 +/- 163 permil)

in hydrated phases possibly present in the CM rock before alteration. The

presence of the D-enriched water signature in Paris might indicate that

transfers of ice from the outer to the inner Solar System have been significant

within the first million years of the Solar System history.

Search for 60Ni excesses in MET-78008 ureilite: An ion microprobe study
KITA N. T., Togashi Shigeko, Morishita Yuichi, Terashima Shigeru, Yurimoto Hisayoshi
Antarctic meteorite research, 11, 11, 103, 121, National Institute of Polar Research, Mar. 1998
English, We have developed a technique for in-situ Ni isotopic analysis using the ion microprobe, in order to detect ^<60>Ni excess from the decay of the short lived nuclide ^<60>Fe (half life=1.5Ma) in ureilite samples. The silicate minerals from MET-78008 ureilite with an old U-Pb age of 4.563±0.006 Ga were analyzed. The ^<56>Fe/^<58>Ni ratios of olivine and orthopyroxene are between 2700 and 5400. In spite of the high Fe/Ni ratios, we could not observe any detectable ^<60>Ni excess. From the mean value of olivine core data, we obtain an upper limit of the ^<60>Fe/^<56>Fe ratio at the time of ureilite formation of 1.8×10^<-7>. The time difference between CAI formation and ureilite formation was estimated to be more than 4 million years, which is consistent with the UPb data from the same meteorite. We concluded that the impact event for the disruption of the ureilite parent body happened more than 4 million years after CAI formation. However, a large uncertainty in the initial ^<60>Fe/^<56>Fe ratio is introduced by the possibility that the ^<60>Ni excess observed in CAIs is of nucleosynthetic origin. Our conclusion may change if the initial ^<60>Fe/^<56>Fe ratio of the solar system using CAI data is too high.

Ion microprobe mesearments of Mg isotopes in Type B1 CAI of Allende meteorite
KOIKE O., Yurimoto Hisayoshi, Nagasawa Hiroshi, Sueno Shigeho
Proceedings of the NIPR Symposium on Antarctic Meteorites, 6, 6, 357, 363, National Institute of Polar Research, May 1993
English, Magnesium isotopes in individual mineral grains of a Ca-Al rich inclusion from the Allende meteorite have been measured by secondary ion mass spectrometry. An electrostatic peak switching system was used to make a precise isotopic measurement in high mass resolution mode (M/⊿M=∿4000). The inclusion shows excess of ^<26>Mg correlated with the ^<27>Al/^<24>Mg ratio. The results suggest that live ^<26>Al decayed in the inclusion which formed simultaneously in the solar nebula. The relative abundance of ^<26>Al(^<26>Al/^<27>Al=3.12×10^<-5>) is close to the "canonical" value (^<26>Al/^<27>Al=∿5×10^<-5>) for coarse-grained CAIs.

Yurimoto Hisayoshi, Chikyukagaku, 51, 2, 49, 59, 2017

Oxygen is the third most abundant element in the Universe and the most abundant element of the terrestrial planets. The presence of oxygen in gaseous, ice and dust phases makes oxygen isotopes important tracers of various fractionation processes to form a protoplanetary accretion disk, which are essential for understanding the evolution of building blocks for planet formation. Photodissociation of CO isotopologues in cold interstellar environments forms H₂O ice with depletion of ¹⁶O component relative to the interstellar CO, but with heritage ¹⁷O/¹⁸O ratio from the interstellar CO. Dynamic evolution of protoplanetary disk generates H₂O enrichments inside snowline of the disk to change from ¹⁶O-rich to ¹⁶O-poor gaseous environments. Thermodynamics during heating processes reset oxygen isotopic compositions of dust in the disk to the gaseous oxygen isotope values. Therefore, building blocks of planet show oxygen isotope variations with variable ¹⁶O component, but with similar ¹⁷O/¹⁸O ratio each other. Oxygen isotopic compositions of outer planets would be ¹⁶O-poor in order of increasing distance from the Sun if outer planet formation started from icy planetesimal accretion.

HAYABUSA 2 and JAXA Astromaterials Research Group -Past, Present, and Future Plan-
Yurimoto Hisayoshi, Abstracts of Annual Meeting of the Geochemical Society of Japan, 63, 0, 135, 135, 2016

The Astromaterials Science Research group of JAXA has been organized in 2015 as successor to the extraterrestrial curation facility. New mission of the group is research oriented in addition to routine operational services to scientific communities. As a result, it is necessary to enhance strong interactive relationship with material scientists of industry-government-academia research communities in the world. In this presentation, I introduce present status of the group with the history and we would like to discuss strategy for the enhancement towards new generation sample return missions of Hayabusa2, OSIRIS-Rex, and MMX.

Why do we want to invent novel analyzers beyond state-of-the-art spectrometer?
Yurimoto Hisayoshi, Abstracts of Annual Meeting of the Geochemical Society of Japan, 63, 0, 102, 102, 2016

Are spectrometers in your laboratory useful to analyze your geochemical problems? Are state-of-the-art spectrometers in the world useful to analyze your geochemical problems? Do you need to invent novel spectrometers to analyze your geochemical problems? I would like to discuss with peoples who answer YES for the last question. Why do we want to invent novel analyzers beyond state-of-the-art spectrometer? Because new geochemical problems, which are difficult to solve by use of state-of-the-art spectrometers, are discovered by yours. Development of novel spectrometers begins collaboration between new types of physics and chemistry, and advance towards discovery of new spectrometer. I would like to discuss the case of isotope microscope, as an example that discovery on geochemistry has been made by an invention of new spectrometer.

Survey of Presolar Remnants Remained in Meteorites by Isotope Microscope
YURIMOTO Hisayoshi, SAKAMOTO Naoya, KENBIKYO, 47, 2, 92, 97, 30 Jun. 2012

Laboratory analysis of space materials is an important method to study origin of solar system. Among the laboratory analysis, microscopy is very useful because space materials have complex and fine structures. Large differences of isotopic composition are common among the space materials. Isotopes can be used as tracers to study origin and evolution of space materials. Conventional mass spectrometry is limited to apply for microanalysis, but recently, isotope microscopy is developed and the situation is gradually changed. The isotope microscopy can obtain precise isotopic image of fine structures of space materials and analyze formation processes of the structure in detail. Here we report studies of oldest materials of the solar system, presolar grains formed in circum stellar, and ice fossils formed in molecular cloud.

CAIとコンドリュールは、原始太陽系星雲内で異なる時間に異なる条件で溶融したと考えられているが、これらの物質の溶融を引き起こした物理的プロセスが同一であるか、その物理的プロセスの詳細は明らかになっていない。本研究では、CAI-コンドリュール複合物質の形成年代および溶融条件を明らかにする事を目的として、SIMSによるAl-Mg系同位体分析を行った。複合物質のオリビンと斜長石は、CAI形成後3.4Myに相当するisochronを形成した。一方で溶融残渣と考えられるスピネルは上記isochronとCanonical isochronとの中間に分布し、そのMg同位体組成は複合物質形成イベントによって不完全に(45-98%程度)リセットされたと考えられる。スピネルのみが溶け残る温度条件は岩石学的に1380-1480℃と見積もれる。スピネル中のMg拡散モデルから、溶融時間は50s-7hと見積もられた, GEOCHEMICAL SOCIETY OF JAPAN, Japanese

二次イオン質量分析は高い空間分解能と多元素の高感度な定量が出来るため微小領域の同位体分析において重用されている。しかしながら希ガスはイオン化ポテンシャルが高いことと含有量が微量であることから、天然試料のSIMSでの分析は不可能であった。そこで我々はLaser Ionization MAss nanoScopeを用いて希ガス同位体分析を天然試料に適応するための開発を行っている。この装置は一次イオンビームによりスパッタされた希ガス原子をフェムト秒レーザーによりポストイオン化させることが可能である。従来の希ガス局所分析の空間分解能は100 μm程度であったが、LIMASではサブミクロン(最高空間分解能10 nm)で分析が可能である。この装置を用いてレゴリスブレッチャの太陽風起源希ガスの2次元分布を分析することにより、小惑星表層を覆うレゴリスの形成過程を明らかにすることが本研究の主題である。, GEOCHEMICAL SOCIETY OF JAPAN, Japanese

Yoshimura Shumpei, Nakamura Michihiko, Yurimoto Hisayoshi, Abstracts for Annual Meeting of Japan Association of Mineralogical Sciences, 2012, 0, 28, 28, 2012
The carbon isotopic fractionation between CO₂-rich fluid and granitic melt was determined to be Δ_f-m = +0.8‰ at 1200 °C and 10 kbar. Infrared spectrometry revealed that both CO₂ molecule and CO₃^2- are present in this melt. The carbon isotope fractionation is modelled as a linear function of the ratio of CO₃^-2 to CO_2molecule., Japan Association of Mineralogical Sciences, Japanese

Development of secondary neutral mass spectrometry using femtosecond laser and its applications to space sample characterization
YURIMOTO Hisayoshi, ISHIHARA Morio, UCHINO Kiichiro, EBATA Shingo, Oyo Buturi, 80, 11, 979, 982, 10 Nov. 2011

We have been developing secondary neutral mass spectrometry using a femtosecond laser for the characterization of asteroidal samples returned by the Hayabusa spacecraft. The secondary neutral mass spectrometry demonstrates analytical potentials of a spatial resolution of 40 nm and the postionization of He atoms. We plan to apply the measurement technique to natural space materials in order to characterize the solar activities of a young sun and determine the age of materials formed beyond the solar system formation.

INOUE Toru, YABUKI Tomomi, YURIMOTO Hisayoshi, Abstracts for Annual Meeting of Japan Association of Mineralogical Sciences, 2011, 228, 228, 05 Sep. 2011
Water contents of Al-bearing minerals in the mantle transition zone and the lower mantle were determined in the systems pyrope - enstatite with H2O of 11.3 wt% and 18.7 wt% at pressures of 20-26 GPa and temperatures of 1473-1873K. The water contents of Al-bearing experimental products were measured by secondary ion mass spectrometry (SIMS) in Hokkaido University, and found the water contents as follows : perovskite ∼0.8 wt%, garnet ∼0.6 wt%, stishovite ∼1.4 wt%, phase D ∼22 wt%. These water contents were strongly related to the Al contents of these phases. Thus the water contents in the Earth' s mantle minerals are strongly related to the Al contents., Japan Association of Mineralogical Sciences, Japanese

FLUOROKINOSHITALITE AND FLUOROTETRAFERRIPHLOGOPITE : NEW SPECIES OF FLUORO-MICA FROM BAYAN OBO, INNER MONGOLIA, CHINA
MIYAWAKI RITSURO, SHIMAZAKI HIDEHIKO, SHIGEOKA MASAKO, YOKOYAMA KAZUMI, MATSUBARA SATOSHI, YURIMOTO HISAYOSHI, YANG ZHUMING, ZHANG PEISHAN, Clay science, 15, 1, 13, 18, 01 Mar. 2011
Two new species of F-mica, fluorokinoshitalite (BaMg_3Al_2Si_2O_<10>F_2) and fluorotetraferriphlogopite (KMg_3Fe^<3+>Si_3O_<10>F_2) occur in Bayan Obo, Inner Mongolia, China. They form subhedral to euhedral platy crystals in metamorphosed carbonate rocks. They are associated with phlogopite, yangzhumingite, and rare earth minerals such as bastnasite-(Ce), cordylite-(Ce), monazite-(Ce), fluorbritholite-(Ce) and huanghoite-(Ce). Fluorokinoshitalite is transparent and colorless with white streak and pearly luster. Cleavage is perfect on {001}. The calculated density is 3.235g cm^<-3>. Fluorotetraferriphlogopite is brown in color with white to pale brown streak. It is transparent showing pearly luster and perfect cleavage on {001}. The hardness is 3-4 on the Mohs scale. The calculated density is 2.966g cm^<-3>. This mineral is optically biaxial (-) with n=1.576 (min.)-1.582 (max.). It shows reverse pleochroism (Z'=colorless, X'=light brown). Electron microprobe analyses with SIMS for Li gave empirical formulae (based on 12 anions); (Ba_<0.56>Na_<0.25>K_<0.06>)(Mg_<2.76>Fe^<2+>_<0.14>Ti_<0.01>) (Si_<2.73>Al_<1.15>Fe^<3+>_<0.12>)O_<10>[F_<1.72>(OH)_<0.28>] and (K_<0.94>Na_<0.02>Ba_<0.01>)(Mg_<2.62>Li_<0.15>Fe^<+2>_<0.14>_Mn_<0.01>)(Si_<3.33>Fe^<3+>_<0.66>Al_<0.01>)O_<10>[F_<1.65>(OH)_<0.35>] for fluorokinoshitalite and fluorotetraferriphlogopite, respectively. The lattice parameters were refined in the monoclinic system (C2/m) with the XRD data obtained with an IP-Gandolfi camera as; a=5.3161 (11), b=9.2082(15), c=10.044(2) Å, β=100.158(18)°, V=483.97(17) Å^3 (fluorokinoshitalite) and a=5.325(3), b=9.217(5), c=10.192(7) Å, β=100.03(5)°, V=492.6(5) Å^3 (fluorotetraferriphlogopite)., The Clay Science Society of Japan, English

始原的隕石中の重水素に富む有機物と水素同位体異常を示さない有機物に対し，ラマン分光分析を行った．重水素に富む有機物とマトリックスのラマンスペクトルには，どちらも，Gバンド (約1580 cm-1)とDバンド (約1370 cm-1)が見られた．これは，隕石有機物が示す典型的なラマンスペクトルである．また，重水素に富む有機物の方が，水素同位体異常を示さない有機物と比較してDバンドの半値幅, DバンドとGバンドの強度比が小さいことが分かった．この結果は，重水素に富む有機物と水素同位体異常を示さない有機物とでは構造が異なることを示唆しており，前者の方が少し構造が単純であると考えられる．, GEOCHEMICAL SOCIETY OF JAPAN

Particles collected by the Hayabusa spacecraft are considered as regolith on the surface of asteroid Itokawa. Three-dimensional structures and shapes of these particles were obtained using X-ray microtomography at Spring-8 in the preliminary examination of Hayabusa sample. The modal abundance of minerals and density of whole particles are similar to those of LL chondrites. Any melting textures, such as agglutinates found in Luna regolith, were not observed. Size distribution and three-dimensional shape distribution are also different from those of Luna regolith. Based on these data, the formation and evolution of the regolith particles will be discussed., GEOCHEMICAL SOCIETY OF JAPAN

Microstructure and its origin of isotopically anomalous material COS in the Acfer 094 carbonaceous chondrite
Seto Yusuke, Toh Shoichi, Sakamoto Naoya, Yurimoto Hisayoshi, Abstracts for Annual Meeting of Japan Association of Mineralogical Sciences, 2010, 0, 153, 153, 2010
In the present study, we report microstructure of the isotopically anomalous material COS in the carbonaceous chondrite Acfer 094 using transmission electron microscopy. The TEM observations shows that COS grain consists of magnetite + pyrrhotite (+ minor pentlandite) with a symplectitic texture in tens nm scale. The grain boundaries between magnetite and pyrrhotite are smoothly rounded, and both phases are directly contacted without amorphous regions. Such a nanometer scale inter-growth texture may suggest the simultaneous and rapid crystal growth of the constituent minerals at the time of formation., Japan Association of Mineralogical Sciences, Japanese

The Hayabusa spacecraft arrived at the asteroid Itokawa in November 2005, and the sample capsule was successfully retrieved in June, 2010. Although the sample collection was not made by normal operations, it is expected that a small amount of sample, at least a few particles of approximately a few tens of micron meters in size, were collected from the asteroid surface. If the sample is present in the capsule, it will be examined preliminary within one year prior to detailed analysis phase. The following scientific achievements will be expected; (a) characterization of the surface material of Itokawa (LL5 or 6 chondrite as expected from reflectance spectrum observation), (b) processes on an ancestor body of Itokawa and accretion into Itokawa (brecciation, degree of impact, etc.), (c) interaction with space environment (proof of space weathering, isotopic composition of solar wind oxygen, etc.), and (d) materials fallen onto the surface (e.g., organic materials without contamination on the earth)., Japan Association of Mineralogical Sciences, Japanese

Aragonite (CaCO₃) makes up coral skeletons. The variation of the trace elements and isotope in coral skeletons is used for reconstructing paleoclimate. The process of skeleton growth plays an important role for interpretation of those data, but Aragonite is a metastable phase under a coral growing environment and the nucleation and growth process has not been raveled clearly. Here we will propose a possible process through observations of mineral texture on nano to micron scale.
The observed materials are massive coral (Porites lobata) and arborescens coral (Acropora nobilis). Each thin section was observed its texture using optical microscope and ATEM for texture analysis and FE-SEM for element distribution., Japan Association of Mineralogical Sciences, Japanese

From petrographic study, a large Allende type B inclusion, Golfball has experienced at least two melting events. In the present study, we report preliminary results of oxygen and Al-Mg isotopic measurements of spinel and melilite in Golfball to determine ages of the multiple melting events and the oxygen isotopic composition of each melt. Delta O-18= -50 to -40permil for spinel, and the oxygen isotopic composition of melilite is distinct in each petrographic occurrence: Delta O-18= -20 to -10permil for gehlenitic core melilite and Delta O-18= ~0permil for melilite in the rim. Two isochrons are defined by the Al-Mg data. The gehlenitic core melilite and rim melilite yield initial ²⁶Al/²⁷Al ratios of 4.9+-0.8 and 1.9+-1.2x10^-5, respectively. The age difference between the two isochrons is calculated to be about 1 My.

In this study, we determine the diffusivity of silicon in forsterite at high pressure and temperature to understand the effect of pressure on diffusivity.We performed high-pressure experiments using a Kawai-type multianvil apparatus. In the experiments, we used single crystal of forsterite as starting material with coating of 29Si-enriched Mg2SiO4 on the polished surface. Thick coating layer (200-300 nm) can maintain the isotope composition constant at the surface during diffusion annealing at pressures of 3, 8, 13 GPa and temperatures of 1600 and 1800 K for 3-60 hours. After high-pressure experiments, the recovered samples were analyzed by a secondary ion mass spectroscopy (SIMS) to obtain the variation of isotope concentration with depth from the crystal surface. Self-diffusion coefficient at 13 GPa and 1600 K is preliminarily estimated to be D=7x10-21 m2/s., Japan Association of Mineralogical Sciences, Japanese

Relationship between the abundance of presolar grains and metamorphic degree in carbonaceous and ordinary chondrites

Presolar grain survey was performed with 2-D in-situ isotope microscopy in carbonaceous and ordinary chondrites of various chemical groups, and various alteration, and metamorphic degrees. The sizes, and chemical compositions of presolar grains were studied with FE-SEM-EDS. A total 56 C-anomalous and 125 O-anomalous grains were found as presolar SiC, graphite, oxide, and silicate. Most of silicates were Fe-rich olivine. The various abundances of presolar silicates among carbonaceous chondrites indicate the destruction of presolar silicates by the parent body process. The lower abundances of presolar silicates in the least metamorphosed ordinary chondrites than carbonaceous chondrites suggests the destruction of silicates by nebular process in ordinary chondrite forming rigion., Japan Association of Mineralogical Sciences, Japanese

Variations of chemical composition of matrices of carbonaceous chondrites

Carbonaceous chondrite Acfer 094 is beliebed to one of the most primitive meteorites. This meteorite contains highly abundance of presolar grains and cosmic symplectite (COS) in the matrix. The COS has not been discovered in other carbonaceous chondrites. The uniqueness of Acfer 094 may be appeared in chemical characteristics of the matrix. In this report, we observed variations of chemical composition of fine-grained matrices among various carbonaceous chondrite groups to compare with Acfer 094. As a result, Al, S and Ca contents of fine-grained matrix minerals are highly variable among the carbonaceous chondrite groups. Acfer 094 matrix has both higher ratios of S/Al and Ca/Al than most chondrite groups. Such difference may result from micro scale elemental redistribution by aqueous and thermal metamorphism. This approach may be useful to classification of chondrite matrix to identify the pristine nature., Japan Association of Mineralogical Sciences, Japanese

A compound CAI found in the Allende meteorite was investigated for its formation processes by means of petrology, chemical composition and oxygen isotopic compositions. The inferred formation processes are as follows: 1) condensation of the precursor CAI from ¹⁶O-rich nebula gas, 2) multiple melting of the precursor CAI, 3) mixing of the precursor CAI with a chondrule-like material by melting under slightly ¹⁶O-rich nebula gas, 4) chondrule-like rim formation., Japan Association of Mineralogical Sciences, Japanese

Development of high-sensitivity ion imager corresponding to real-time readout
Sakamoto Naoya, Aoyama Satoshi, Kawahito Shoji, Yurimoto Hisayoshi, Abstracts for Annual Meeting of Japan Association of Mineralogical Sciences, 2009, 0, 230, 230, 2009
High-sensitivity ion imager corresponding to real-time readout with 250000 pixels is developed. The output signal fluctuation of the pixel caused by 1 incident ion was 150µV/ion pixel which is 5 times improved by adopting smaller pixel capacitance. In order to reduce the readout noise, multiple signal-sampling mechanism was incorporated. The readout noise was achieved to 250 µV corresponding to 1.7 ions with 16 times signal-sampling. The readout speed was achieved to 12.5 frames/sec with single sampling and 8.3 frames/sec with 16 times signal-sampling. The read noise is independent of read out speed and now optimizing with multiple signal-sampling mechanism. Therefore, real-time single ion detection is expected if all the parameters become optimized., Japan Association of Mineralogical Sciences, Japanese

This special issue of "Chikyu Kagaku" contains five papers from three sessions for cosmochemistry, "Cosmochemistry of extraterrestrial materials: From presolar history to early solar history", "Origin and evolution of Moon, Mars and small bodies in the solar system", and "Analytical technique, analytical organization and the scientific results of a new age of sample return mission", in the annual meeting of the Geochemical Society of Japan 2008. The five papers cover several topics on formation of water molecules in circum stellar environments, noble gas compositions of individual chondrules, discovery of chondrules from a comet sample, new analytical technique of extraterrestrial organics, and advances of lunar science under the cosmochemical view. These papers should be helpful to understand the trends of current research subjects of cosmochemistry. We hope this special issue could act as useful media for the cosmochemical community and the new comers to this research field., The Geochemical Society of Japan, Japanese

We report mineral characterization of the isotopically anomalous material "COS" in the carbonaceous chondrite Acfer 094 using synchrotron radiation X-ray diffraction analysis and transmission electron microscopy. The results show following clear differences between the samples having high Ni content (High-Ni COS) and low Ni content (low-Ni COS); (1) The high-Ni COS grain consists of magnetite + pentlandite, while the low-Ni one consists of magnetite + pyrrhotite. (2) The high-Ni one is an aggregate of magnetite-pentlandite showing a symplectitic texture in tens nm scale, while the low-Ni one is an aggregate consisting of idiomorphic magnetite (∼100nm) and pyrrhotite (∼50nm) grains.We infer that the COS grains were formed by sulfurization and oxidization of metal grains. The chemical and micro-structural differences are probably reflected in the texture and the chemistry of precursor materials before the oxidization., Japan Association of Mineralogical Sciences, Japanese

Microstructure Observations on Coral Skelton

Mineral phase identification of the coral skeletal microstructure is important for reconstructing the paleo-climate. Especially, chemical composition of Porites sp. is widely used as a paleo-environment variant. For example, it is believed that Sr/Ca ratio in coral skeletons is sensitive to temperature of seawater. Recently, Greegor et al. (1997) reported that as much as 40% of strontium (Sr) in coral aragonite existed as a SrCO₃ end member by using XANES and EXAFS. This should be a very serious problem, when we apply the Sr/Ca ratio to reconstruct the paleo-environment. However, since there has been no direct mineral identification of SrCO₃, we have carefully observed Porites sp. by FE-ASEM and ATEM in order to identify mineral phases in the coral skeletal., Japan Association of Mineralogical Sciences, Japanese

New technology of mass spectrometry for isotope analyses has been greatly advanced for recent years. The advances are especially for improvements of precision and for microanalysis. Precisions of isotope ratios have been improved by using an inductively coupled plasma mass spectrometer with multiple ion collectors. Capabilities of microanalysis have been improved by secondary ion mass spectrometry. These advances introduce new insights for origin of the Solar System and evolution of the Earth., Japan Association of Mineralogical Sciences, Japanese

Massive corals have been widely used as proxies for past changes in sea surface temperature (SST) of the tropical and subtropical oceans because the oxygen isotopic and strontium/calcium (Sr/Ca) ratios of their aragonitic skeletons are believed to vary as a function of the temperature of the ambient seawater. However, recent microanalytical studies using secondary ion mass spectrometry (SIMS) have revealed large chemical heterogeneities for Sr/Ca and oxygen isotopic ratios in coral skeleton, which cannot be explained by temperature variation (e.g. Meibom et al., 2004, Rollin-Bard, et al., 2003), GEOCHEMICAL SOCIETY OF JAPAN

Trace Element Study of Clinopyroxenes from Garnet and Spinel Peridotite Xenoliths of the Burkal River

Trace element chemistry of clinopyroxene in the mantle xenoliths from melanephelinites of the Burkal volcanic group has been studied. The Burkal group is composed of several local outcrops of 5-8 Ma melanephelinites within the Khentey domal uplift near the Russia/Mongolia boundary. Cr-diopside group xenoliths include garnet and spinel lherzolite, spinel harzburgite and dunite, and garnet and spinel pyroxenites. Hydrous minerals were not detected, however shallow mantle feldspatic metasomatism is present. Clinopyroxene from garnet lherzolites has high TiO_2, Al_2O_3, and Na_2O relative to clinopyroxene from spinel lherzolites. Olivine has composition of Fo_<90-92>. Spinel has Mg#=60-80 and contains 10-46 wt.% Cr_2O_3. Clinopyroxene from garnet lherzolites has REE patterns typical for fertile peridotites. Trace element patterns of clinopyroxene from depleted spinel peridotites show progressive depletion in HREE and HFSE and enrichment in LREE toward more depleted varieties of harzburgites and dunites. REE patterns of clinopyroxene in harzburgites are strongly U-shaped and have (La/Sm)n=5-36 and (Sm/Yb)n=0.4-2.1. Clinopyroxene in harzburgites has also extremely low Zr content (0.4-3.4ppm) and high Ti/Zr ratio ranged in 190-240. The patterns of clinopyroxene in depleted peridotites are indicative of significant partial melting (up to 15-20%) of the primary substrate followed by cryptic metasomatic enrichment by silicate or carbonatitic melt. Estimation of T-P parameters for garnet lherzolites reveals equilibration at 17-23 kbar (60-90km depths) and 1050-1150℃. T-estimations for harzburgites and dunites indicate, that they may form veins at 50-70km depth, whereas shallow mantle (low-T) depleted peridotites were not detected. The uppermost mantle may be composed of fertile spinel lherzolites., 東北大学, English

Cation diffusion in wadsleyite and the rheology of subducting slabs

Diffusion experiments of mantle minerals are important for understanding the rheological properties of the Earth's mantle and subducting slab, because the atomic diffusion in the crystals controls plastic deformation in silicate minerals. Wadsleyite is a major constituent mineral in the mantle transition zone. Hence experimental examination of the diffusion rates is essential for debating the rheology of mantle transition zone. In this study, Si self-diffusion rates in wadsleyite were measured at 18 GPa, 1703-1903 K and the viscosity of wadsleyite deformed by diffusion creep was calculated. Our results imply some portions in cold subducting slabs, where the grain size reduces to less than 1 micron after the olivine-spinel transformation, become weaker than the surrounding mantle., Japan Association of Mineralogical Sciences, English

Makide Kentaro, Kobayashi Sachio, Yurimoto Hisayoshi, Abstracts of Annual Meeting of the Geochemical Society of Japan, 51, 0, 249, 249, 2004
Acfer214中の酸素同位体組成は、個々のCAI中で均一であるが、異なるCAI間に16O-richから16O-poorに至る約50‰の巾に分布している(Kobayashi et.al,2003)。本研究は26Alの存在と酸素同位体組成の不均一の相関を明らかにするため、Acf214中の酸素同位体組成の異なる６つのCAIについて二次イオン質量分析計(Cameca ims-1270)を用いてAl-Mg年代測定を行った。結果すべてのCAIについて26Mgの過剰はなく、26Alの存在と酸素同位体異常の程度に相関はなかった。これらの結果は原始太陽系円盤進化に次のような制約を課す。(1)Al-Mgシステムが時計として働くのであれば、CAI形成は原始太陽系円盤において300万年以上継続しその間酸素同位体不均一が円盤内に残っていた。もしくは、(2) 26Alと酸素同位体の不均一が円盤内に存在してこの両者の分布は相関がなかった。, GEOCHEMICAL SOCIETY OF JAPAN

The Origin of Plagioclase in Peridotite Xenolith from Tallante, SE Spain: Subsolidus or Melt Impregnation?
SHIMIZU Yohei, Arai Shoji, Yurimoto Hisayoshi, Gervilla Fernando, Abstracts of Papers Presented at the Annual Meeting of The Japanese Association of Mineralogists, Petrologists and Economic Geologists, 2003, 0, 80, 80, 2003
(はじめに)<br>斜長石かんらん岩は地殻の薄く地温勾配の高い海洋底マントルにおいて一般に存在すると考えられている。海洋底から得られるかんらん岩中の斜長石の起源については、サブソリダス下での反応ではなく、トラップメルトからの晶出が大半であるらしい(Dick, 1989) 。南東スペイン、タジャンテにおけるかんらん岩捕獲岩にも斜長石かんらん岩が存在する。本発表では、タジャンテのかんらん岩における斜長石かんらん岩の起源について議論する。<br>(かんらん岩について)<br>スペイン南東部タジャンテ周辺域には中新世にカルクアルカリ火山活動が、それに引き続き鮮新世にマントル捕獲岩を包有したアルカリ玄武岩が噴出した。超苦鉄質捕獲岩類は、Frey and Prinz (1978)でいうところの、Group I（レールゾライトからハルツバージャイト）と、母岩と同じマグマソースを持つとGroup II(クライノパイロクシナイト)に分けられる。これらの岩石は複合捕獲岩(Irvine, 1975)を形成することがある。Group Iの岩石は鉱物組み合わせにより、スピネルかんらん岩と斜長石かんらん岩の2つに分類される。Group Iにはしばしば斜方輝石-斜長石脈が観察され、最も太い脈では石英を伴い、その起源としてはスラブ起源のSiに富むメルトが考えられている(Arai et al. 2003)。Group IIと複合捕獲岩を形成するGroup Iの岩石、または斜方輝石-斜長石脈を含む岩石では斜長石が多く観察されるが、それらと無関係の独立した捕獲岩でも斜長石が見出される。<br>(鉱物化学組成について)<br>かんらん石のFo値とスピネルのCr#(=Cr/(Cr+Al)原子比)の関係において、スピネル、斜長石かんらん岩とほぼ同じスピネルCr#（0.15-0.22）をもつが，後者の方がより低いFo値をもつ（スピネルかんらん岩：Fo90.5-91、斜長石かんらん岩Fo89.8-90.8）。また、単斜輝石のAl2O3、Cr2O3量を比較するとスピネルかんらん岩は斜長石かんらん岩より高く，TiO2wt%は斜長石かんらん岩のほうが高い。東工大に設置されているSIMSにより求められた単斜輝石中の微量元素存在量のうち、La/Yb比はスピネルかんらん岩、斜長石かんらん岩はそれぞれ1.32-1.99、0.70-1.84であるのに対し、斜方輝石-斜長石脈を含むサンプルにおいては1.57-4.71と比較的高い値を示す。REEパターンにおいてはスピネル、斜長石かんらん岩は、後者がEuの負異常を持つ点を除いて、ほぼ似たいようなフラットなパターンを示すのに対し、脈を持つサンプルはLREEにエンリッチしたパターンを示す。<br>(議論＆まとめ)<br>スピネルかんらん岩は圧力低下に伴い斜長石かんらん岩へとサブソリダス変化することが知られている(Kushiro and Yoder, 1966)。しかしながら、この反応は系のCr/Al比に影響を受け、Cr/Al比が高い岩石ほどこの反応曲線はより低圧側へと移動することが知られている。一連の様々な枯渇度を有するスピネルかんらん岩が減圧した後、高枯渇度の部分はそのままで、低枯渇度の部分にのみ斜長石が形成されることが起こり得る。タジャンテでは一見これが起きているように思える。そのことは微量元素の検討からも指示され、スピネル、斜長石かんらん岩はほぼ同じようなREEパターン、La/Yb比を持つのに対し、外界からのメルトの影響を受けたサンプルはLREEにエンリッチしたパターンに変化したことが明瞭である。したがって、タジャンテの斜長石かんらん岩は外部からのメルトの侵入を受けて形成されたものではなく、サブソリダス変化によってもたらされたと結論づけられる。, Japan Association of Mineralogical Sciences

オリビンの高圧相であるwadsleyiteは，地球内部のマントル遷移層における主要構成鉱物であり，wadsleyite中の原子の拡散速度を測定することは，マントル遷移層のレオロジーやダイナミクス，電気伝導度を議論するうえで重要である。本研究では15-18.5GPa, 1473-1973Kにおいてwadsleyite中のMg-Feの相互拡散実験を無水と含水条件下で、またSiの自己拡散実験を無水条件下で行った。それらの結果からマントル遷移層の含水量と電気伝導度，およびマントル遷移層のレオロジーに関して考察を行う。<br> 高圧実験は東北大学理学部設置の3000 ton 川井型高圧発生装置（MAP-3000）を用いて行った。Mg-Fe相互拡散実験では、Mg#90とMg#100のwadsleyite多結晶体を接合し、酸素分圧はNi-NiOバッファーで制御しながら実験を行った。FTIR測定により、無水条件下では0.01 wt.%以下、含水条件下では0.02-0.23 wt. %のH₂Oがwadsleyite多結晶体中に含まれていることがわかった。拡散実験後， EPMAを用いて拡散プロファイルを測定し拡散係数を算出した。wadsleyite中のMg-Fe相互拡散には組成依存性があり，Boltzmann-Matanoの解析法を用いて拡散係数を求めた結果，Fe 成分が多いほど拡散速度は速くなることがわかった。無水条件下ではMg-Fe相互拡散の活性化エネルギーは156kJ/molと求められた。16 GPa, 1200 °C における wadsleyite中のMg-Fe 相互拡散係数は，無水条件下で1.85×10^-14 m²/s, 含水条件下で5.53×10^-13 m²/s と求められた． wadsleyite中のMg-Fe 相互拡散係数は，0.02-0.23 wt. %のH₂Oの存在下で約3倍速くなる。また含水量が多いwadsleyiteについては，粒界拡散の寄与も認められた。Schultz et al. (1993) による地球内部の電気伝導度観測とMg-Fe相互拡散係数から計算した電気伝導度を比較した場合，マントル遷移層には約0.2 wt. %程度のH₂Oが存在する可能性がある。<br> Si自己拡散実験では、出発物質としてwadsleyite多結晶体表面に拡散源となる29Siに富んだSiO₂を蒸着したものを用いた。拡散実験後，東京工業大学設置の二次イオン質量分析計(SIMS)によるDepth profile法を用いて29Siの拡散プロファイルを作成し，拡散係数を算出した。拡散プロファイルは粒内拡散と粒界拡散が寄与している二つの領域からなる。粒内拡散が寄与している領域について薄膜状拡散源に対する解法をもちいて粒内拡散係数(Dv)を求め、粒界拡散が寄与している領域についてはLe Claire（1963）による解法を用いて粒界拡散係数(_Dgb)を求めた。Si自己拡散の活性化エネルギーは、粒内拡散の場合273kJ/mol、粒界拡散の場合254kJ/mol と推定された。Wadsleyite中のSiの拡散速度は，Mg-Feの相互拡散速度と比較して約6桁遅い。また，Dohmen et al. (2002) によるオリビン中のSiの拡散速度よりも1桁程度高くYamazaki et al. (2000) によるペロブスカイト中のSiの拡散速度と同程度であった。得られた拡散係数を用いてwadsleyiteが拡散クリープによって変形した際の粘性率を計算した。また，転位クリープによって変形した際の粘性率をKarato et al. (2001) によるクリープパラメーターを用いて計算した。それらの結果と地球物理学的観測による粘性値を比較して，マントル遷移層では拡散クリープおよび転位クリープの両方の変形メカニズムが卓越する可能性がある。また沈み込むスラブの低温条件では拡散クリープが卓越していることが予想され，この場合は相転移に伴う結晶粒径の細粒化によってプレートが軟化する可能性がある。, Japan Association of Mineralogical Sciences

Partitioning of H₂O between upper mantle, mantle transition zone and lower mantle

（はじめに）<br> 水は地球表層に大量に存在する主要な揮発性成分の1つであり、その水がスラブの沈み込みによって常に地球内部に供給され、鉱物の物性や溶融温度に大きく影響を与えることが明らかにされてきている。特にマントルの主要構成鉱物はカンラン石であり、その高圧相のwadsleyite, ringwooditeには3wt%ものH₂Oが結晶構造中に含まれうることが明らかにされてきてはいるが、実際の水の存在割合を議論する場合、それらの鉱物間の水の分配が重要で、マントル中のどの層に相対的にどれぐらい水が存在可能かということを知る必要がある。現在までolivine-wadsleyite間（Chen et al.,2003）、及びwadsleyite-ringwoodite間（Kawamoto et al., 1996）でこのようなデータが報告されているが、特に後者ではデータは１点だけである。本研究ではオリビンの高圧相転移のwadsleyite-ringwoodite、及びringwoodite-perovskite間における水の分配を明らかにし、上部マントル、マントル遷移層、及び下部マントル間の水の分配を明らかにした。<br> （実験方法）<br> 本研究の含水系の出発物質には(Mg_0.8Fe_0.2)₂SiO₄+16wt%H₂OになるようにFe₂SiO₄, Mg(OH)₂, SiO₂の混合粉末試料を、無水系には(Mg_0.8Fe_0.2)₂SiO₄になるようにFe₂SiO₄, MgO, SiO₂の混合粉末試料を用意した。実験装置は愛媛大学設置のマルチアンビル型高圧発生装置を使用し、wadsleyite-ringwoodite間の水の分配を求める実験は14.6～17.0GPa、1400℃の条件下で、ringwoodite-perovskiteの水の分配を求める実験は～23.5GPa、1600℃の条件下で行った。今回の実験は含水量測定に耐え得る大きな共存結晶を得ることを目的としているので、比較的大きい含水量を選択し、また温度も含水ソリダス直上になるよう設定した。実験は目的の圧力まで加圧、圧力を一定に保ちながら加熱した後、急冷減圧し回収した。回収試料は顕微ラマン分光装置、及び反射電子像により相の同定を、さらにエネルギー分散型電子顕微鏡により化学組成を測定した。また含水量は東京工業大学設置の二次イオン質量分析計により測定した。<br> （実験結果）<br> 含水系で含水量測定に耐え得る50μm以上のwadsleyite及びringwooditeの共存結晶、及びringwoodite及びperovskiteの共存結晶を合成することに成功し、この共存結晶間での水の分配が明らかにできた。Wadsleyiteとringwoodite間の水の分配係数は５点で制約できたが約2程度となり、これはKawamoto et al.(1996)での値(2.5)と近い値を示した。またringwooditeとperovskite間の水の分配係数は約10かそれ以上となった。我々の以前の研究（Chen et al.,2003）によりwadsleyiteとolivine間の水の分配係数は約5程度と明らかにされているので、410km以浅の上部マントル、410-520km及び520-660km間のマントル遷移層、及び660km以深の下部マントル間での水の分配は4:20:10:1ということになる。すなわち、マントル遷移層に極めて高濃度に水が保持され、地球内部の水の貯蔵庫となっていることが考えられる。, Japan Association of Mineralogical Sciences

炭素質隕石を初めとする始源的隕石は太陽系初期に形成された。これら隕石中には太陽系形成以前に存在した恒星の放出物から形成された微粒子が太陽系形成時の加熱による蒸発，溶融をのがれ，それら隕石中にごく少量含まれている．これらは一般にプレソーラーグレインとよばれる。 従来プレソーラーグレインの分離回収にはシカゴ大学のグループが開発した酸を用いて隕石を分解する方法が広く用いられている(Amari et al., 1994)．シカゴグループの方法はシリケイト成分をフッ酸を用いて除去し，その残査からプレソーラーグレインを見つけ出す方法である．現在までに報告されているプレソーラーグレインのほとんどがこの方法で分離，回収された物である．本研究ではNaOHを用いた岩石融解法(Chan et al., 1983)を用いて炭素質コンドライト中のシリケイト成分を融解し，その残渣を同位体分析しプレソーラーグレインを分離する方法の開発を行った．異なった方法でシリケイト成分を除去することにより，今までの結果を独立に検証することができ，また新しい組成や形状のプレソーラーグレインを発見することが期待できる．, GEOCHEMICAL SOCIETY OF JAPAN
