Outline of Final Research Achievements

It is very important to understand the Hadean Earth for decoding the history of the earth. However, it is difficult to directly study the Hadean Earth because geologic recode over 4.03 billion years before is not preserved yet. Thus, we tried to decode the evolution of the early Earth through establishment of an analytical method of 146Sm-142Nd isotope system, geological investigation of the Early Archean geologic terrains, and chemical and isotopic analysis of the Early Archean rock samples. We found the oldest rocks of 4.27 Ga mafic rocks and 3.95 Ga supracrustal rocks, evidence for the plate tectonics and organism from the 3.95 Ga Nulliak supracrustal belt, and the large-scale early differentiation and later homogenization. All of them are new discoveries, and give a significant insight into early earth evolution.

Academic Significance and Societal Importance of the Research Achievements

現在の地球では磁場や火山活動があり、非常に多種多様な生命が生息する。こうした地球がどのように誕生し、進化してきたのかを知ることは人類共通の命題であろう。本研究はその後の地球史を決定づけた初期地球の進化を解読することで、この問題に取り組んだ。その結果、これまで国内では分析することのできなかった146Sm-142Nd分析法の確立、地球最古の岩石や生命およびプレートテクトニクスの証拠や初期大規模分化と比較的早期の均質化の新知見の発見といった多くの成果を得ることができた。これらの成果は国内のみならず海外の新聞やNHKなどのメデイアにも取り上げられ、日本のみならず世界全体の教養知の涵養に貢献した。
