    【遺跡調査】 ヨルダン、モンゴル、インドネシア、北海道における遺跡調査を予定通りに行い、研究課題に直接関わるオリジナルの考古記録の収集を行うことができた。ヨルダンとモンゴルに共通して採取されたInitial Upper Paleolithicの記録は、ヨルダンではホモ・サピエンスの定着（旧人の絶滅）、モンゴルでは拡散初期に相当する貴重なものである。インドネシアでも3万年前近くに遡る記録が得られた。今年度も調査現場において異分野連携を推進し、B01班の文化人類学者がヨルダンの遺跡調査に参加した。
    【海外研究】 連携研究者2名が海外研究を行い資料調査や試料分析を行った。中国黒竜江省ハルビン市と大慶市大慶博物館の訪問では、後期更新世後半から最終氷期最盛期（LGM）にかけての動物骨標本を観察した。また国際活動支援予算により、ドイツ、テュービンゲン大学の地球科学分野の研究室において遺跡出土動物遺存体の同位体分析を行った。
    【試料分析】 遺跡調査で得られた標本は、班内外の研究者との連携を通して分析が進められた。公募研究として進められているタンパク質分析による動物種の同定は、1万年前よりも新しい標本（新石器時代）については安定した結果が蓄積したため、今年度は3万年前に遡る標本（上部旧石器時代）の分析を開始した。
    【成果発信】 ホモ・サピエンスの拡散と定着プロセスに直接関わる考古記録の1つであるInitial Upper Paleolithicの特集号（Archaeological Research in Asia）が分担者の出穂雅実を主体として編集された。また、2018年12月に京都で国際研究会を開催した。
    【若手育成】 遺跡調査やシンポジウムへの大学院生の参加、および資料分析を通した学士・修士・博士研究の指導を行った。

    We clarified the internal structure of obsidian lavas from the following three localities; Shirataki in the north Hokkaido, Kozushima, one of the Izu islands, and the Kamchatka Peninsula in Russia. Based on the layer structure in obsidian lava and the rock texture and composition, we presented a formation model of obsidian caused by the promotion of outgassing and of rhyolite by leaving air bubbles through the cooling process of highly viscous magma.
    We constructed a systematic archeological obsidian research in Hokkaido. We made it possible to identify the sources of obsidian artifacts by the most practical and accurate method of combining X-ray fluorescence and neutron activation analysis. Analyses of more than 3,400 obsidian artifacts of the late Paleolithic sites in Hokkaido suggest that the behavior pattern of the hunter-gatherer group and accompanying obsidian procurement behavior changes with time as a boundary at the late glacial maximum of about 20,000 years ago.

    This study addressed the question as to the extent to which obsidian hydration dating has validity under the different climatic regimes recorded at the scales of regions and archaeological sites. I performed observations and measurements of obsidian hydration rims on archaeological specimens from the prehistoric sites located in various climatic zones including temperate and subarctic, as well as temperate zone in the Atlantic Ocean. The principal method of observation was thin-section method using the petrographic microscope, while selected hydration rims in a portion of samples were also observed using the secondary ion mass spectrometry that allowed one to measure the depths of hydrogen irons. The major results of this study are that estimated hydration rates not only vary depending on the climatic zones but also change in response to variations in endemic conditions notably obsidian provenances and water contents within a single obsidian provenance.

    The present research discussed the process of appearance of Upper Paleolithic in Japanese Archipelago, through examine the northern route for the first modern human in the Last Glacial from Archaeological and Anthropological point of views. Hunter-Gatherer were targeted group mammals that inhabited cold grass-land and open forests during the LGM, particularly about 26,000-22,000 cal yr BP. However, the change at the LGM was not just a replacement of the small flake industry by microblades, but a divergence of the Flake-based, Blade-based, and Microblade-based toolkits.
    In addition with these result, the late Pleistocene radiocarbon chronology of the Transbaikal to conclude that humans completely abandoned the area between 25,000 and 22,000 cal yr BP, suggested us Hokkaido to serve as a refuge and the origin of microblade technology.

  • An exploitation of new obsidian hydration dating toward the establishment of reliable chronology in prehistoric sites and the estimation of paleoclimatic conditions

    NAKAZAWA Yuichi
    The goal of present research is to explore the new research direction of obsidian hydration dating (OHD). Toward the establishment of reliable chronology of prehistoric sites and estimation of paleoclimatic conditions, I examined as to whether and to what extent OHD works. A procedure to choose reliable measurement was proposed through a systematic comparison of variation in rim thicknesses within and between the specimens. Site dates were estimated by using the mean rim thickness that was systematically chosen from the samples. The mathematical formula to estimate the effective hydration temperature (EHT) proposed by Rogers (2007) was employed. The difference between EHT for studied early Holocene site and mean temperature based on the local meteorological data indicated that both Holocene climatic maximum and changes in depths of samples in response to the accumulation of sediments had effects on EHT.
