Outline of Final Research Achievements

More than 200 grains of Hadean zircons (the Earth’s oldest material) were captured by a newly made machine, Automatic Zircon Separator, and by U-Pb dating. By comparing these with lunar rocks, we obtained the first solid evidence for the ABEL bomberdment that occurred in the near-Sun domain of the early Solar System. We could detect also bio-essential elements, such as carbon, in zircons, which suggest the readiness of the Earth’s surface to beget life already at 4.37 Ga or earlier. The high-resolution visualization of 3D heterogeneity of mantle became possible by seismic tomography analysis. Possible remnants of hadean crust were detected in the bottom of mantle. A sharp signal of extraterrestrial material flux was detected from 250 Ma deep-sea strata, and this first enables the same from the material of the Hadean, during which more frequent flux is assumed in the early Solar System.

Academic Significance and Societal Importance of the Research Achievements

太古代岩石の研究から、生命はすでに冥王代に誕生していたとされるが、冥王代岩石は未発見で、主に惑星形成理論や隕石/月の石など地球外試料のみに基づいて、冥王代の地球表層および生命の起源が議論されてきた。本研究でジルコン選別専用装置の開発と大量のジルコンU-Pb年代測定を行なった結果、43.7億年前に表層地殻の大更新を起こす事件、おそらくABEL爆撃がおきた最初の物証が得られた。また、その時点で炭素などの生命誕生を可能にする元素が地表に用意されていたことが判明した。日本の研究で、生命の起源について地球最古物質から初めて冥王代表層環境の情報を得て、人類共通の興味である生命の起源解明に貢献した。
