Outline of Annual Research Achievements

最終年度にあたり、これまでの研究成果を論文としてまとめることに注力した。2017 年に発行されたGeoscience Frontiersの特集号”Frontiers in Early Earth History and Primordial Life-Part I”につづく”Part II”が2018年に発行された。Part IIには冥王代生命学全体から合計7編の論文が出され、このうち5編の論文はA01班の成果(あるいは共著)である。また、成果を日本語で分かりやすく解説することを目的として、地学雑誌特集号「冥王代の世界」を企画し、”Part I-ハビタブルトリニティ惑星の誕生”ならびに”Part II-生命誕生場の準備”として合計13編(A01班関連論文は10編)を発表した。さらに”Part III-生命誕生と初期進化”も整い次第、2020年度前期に発行される予定である。
本年度の研究推進方策については下記のとおりである。
[1]生命誕生場と先駆的化学進化のプロセスの解明:岩石―水相互作用による二次変質に伴って生成する低温の変質鉱物が金属たんぱく質の合成反応に関与するプロセスの再現実験を行った。また、冥王代型の環境下で生きている化石生物の分類を進め、微生物ゲノムの系統的解析に向けた、世界標準の地下水生態系を確立するための予備調査を行った。
[2]冥王代地球表層環境進化のモデルのまとめ:地球が生命惑星となった出発原因を説明した新しい地球形成モデル「ABEL(生命元素降臨)モデル」はすでに論文となったが、炭素循環の定量的な議論に向けて、A05班と共同作業を進め、「生命惑星存続」の条件の概要を明らかにした。
[3]オクロの自然原子炉の研究:ガボン共和国オクロの自然原子炉の層準を貫く掘削を完了した。
[4]地球のような生命惑星を生むことが可能な原始惑星円盤の初期条件を探る:CAIに残された原始惑星の初期条件、および、ABEL爆撃時代に絶妙の揮発性物質の量が降臨した条件の概要を明らかにした。
