Three important conclusions are as follows:(1) the H2O content in garnet and omphacite can be up to 2000ppm and 3000ppm by weight respectively, indicating that they are significant carrier recycing surficial water into deep earth;(2) the heterogeneous distribution at the small scale of the H2O content and hydrogen isotopic ratios suggest that the whole subduction- exhumation process should be very fast;(3) the regular decrease of H2O content from rim to core within some garnet and omphacite grains indicates that hydrogen diffused out from mineral lattice during exhumation in response to sharp pressure decrease, and such hydrogen is expected to be involved in the early-stage retrograde metamorphism.
取得的主要科学认识包括：(1)石榴石和绿辉石的结构水含量可以分别高至2000ppm和3000ppm，这表明它们是板块俯冲过程中将地表水携带进地球深部的重要载体；(2)水含量和氢同位素组成表现出小尺度的不均一分布，说明板块的俯冲和折返过程是十分快速的；(3)在板块折返的早期，由于压力的降低，矿物中的H 会发生不同程度和尺度的扩散，这是早期退变质流体的重要来源。

Several main results on the evolutions of the life and environment on early earth are summarized as follows:(1) the oxygenation of surface environment didn''t cease until a stable stage for 0.4Ga appeared after 1.6Ga;(2) compared to the isotopic compositions of kerogens and coexisted carbonates, the differences between two can effectively carrier the signals from local environments and bio-assemblages;(3) multiple isotopic relationships between kerogens and individual alkanes in Proterozoic samples were observed, which would depend on the specific biogeochemical processes;(4) repeated biogeochemical changes were observed accompanying Neoproerozoic glaciations, which suggesting that environmental rather than evolutionary forces were driving the biogeochemical changes;(5) the bio-radiations after Neoproterozoic glaciations were definitely suggested by molecular and isotopic data to be at the early Cambrian and after the middle of Doushantuo deposition with different triggers for them.
研究获得以下重要认识：（1）古元古代地表环境的氧化可能一直持续到中元古代早期(约1.6Ga)，而在此之后的4亿年里则保持相对稳定；（2）相对于传统的干酪根和碳酸盐的碳同位素组成，二者之差则能更好反映区域环境的演化特征；（3）在元古代干酪根与单体烷烃类之间存在多种碳同位素组成关系；而其与不同的生物地球化学过程有关；（4）全球海洋生物地球化学特征随新元古代多次冰期出现循环波动，这显然为环境因子的驱动；（5）在新元古代大冰期之后，分子与同位素数据显示地球生命在陡山沱中后期和早前寒武纪出现两次大辐射，然而两次生命辐射的本质却是不同的。
