Summary of this work is as follows : 1 Descriptive works (number of papers ; 32 by Maruyama, 9 by Isozaki, 8 by Nakashima and 8 by Yurimoto), 2 Synthetic works (Maruyama ; Dynamics of plumes and superplumes through time, in Superplumes ; Beyond plate tectonics, Springer, 441-502 ; Isozaki ; Plume winter scenario for Biosphere catastrophe, ibid, 409-439, Springer), 3 Detailed fossil and geochemical analysis for P/T boundary, end Proterozoic and end Archean times using drilled cores (5 papers by Isozaki, 2 papers by Nakashima, Yurimoto and Maruyama), 4 SIMS spot analysis for the oldest fossils at 3.56Ga from W. Australia (unpublished by Yurimoto), 5 New discrimination diagram for the type of bacteria by Nakashima (in prep.). Most of these descriptions can be interpreted by the secular cooling of the Earth, but not all. One of the exciting events might be starburst in our Galaxy, and resultant cosmic radiation which may have evolved life in genome level.

本文的工作总结如下：1描述性作品（论文数量;丸山32篇，矶崎9篇，中岛8篇，百合本8篇），2部综合著作（Maruyama ;动力学的羽流和超级羽流通过时间，在超级羽流;超越板块构造，施普林格，441-502 ;矶崎;生物圈灾难的羽流冬季情景，同上，409-439，Springer），3使用钻孔岩心对P/T边界、元古代末期和太古代末期进行详细的化石和地球化学分析（Isozaki等5篇，Nakashima，Yurimoto和Maruyama等2篇），4个西姆斯点分析，对3.56Ga的最古老化石进行了研究。澳大利亚（Yurimoto未发表），5 Nakashima的细菌类型新判别图（编写中）。这些描述中的大多数都可以用地球的长期冷却来解释，但不是全部。其中一个令人兴奋的事件可能是我们银河系的星爆，以及由此产生的宇宙辐射，这些辐射可能在基因组水平上进化出生命。
