Outline of Final Research Achievements

The exact location, magnitude, and mode of Australasian Tektite Event (AATE), a large impact event that occurred ca. 800 ka at somewhere in Indochina Peninsula, has been unknown in spite of its young age and probable large magnitude. In this study, we identified its ejecta deposit in on-land Indochina Peninsular for the first time, specified the impact location as in the western part of Bolaven Plateau, southern Laos, and estimate its crater size as between 15 and 20km in diameter. We also discovered microtektite of AATE at IODP site U1422 in the northern part of Japan Sea that extended its distribution limit to the northeast by over 2,000 km. Stratigraphic estimation of the AATE microtektite layer at U1426 is 792ka, which is conformable with previous estimation of its age by radiometric dating but with better precision.

Academic Significance and Societal Importance of the Research Achievements

2013年のチェリャビンスク隕石の空中爆発は広範囲に大被害を引き起こし、小天体衝突の脅威とリスク評価の必要性が広く認識された。AATEを引き起こした小天体は直径数km、衝突頻度は百万年に1度程度と推定され、人類が遭遇した最大の小天体衝突である。従って、その衝突規模や様式、環境への影響を正しく評価することは、リスク評価の観点から重要である。また、その衝突がジャワ原人の大量死を引き起こした可能性が指摘されており、前期更新世末~中期更新世初頭における人類を含む動物の移動や地域的絶滅に深く関与した可能性が高いため、その衝突の実態解明を行った本研究の意義は社会的にも学術的にも大きいと言える。
