项目摘要
The objectives of this research are to understand the distributions of Archean microbes in space and in time, to understand in what geochemical environment the microbes inhabited, and to study the geophysical controlling factors on the co-evolution of life and environmenta. In 2004, we drilled another hole to collect the core which cuts through the Tumbiana Formation (2.76Ga). We had failed to obtain this formation in the 2003 drilling project. The American research group (Deep Time Drilling Project) collaborated us in this year's project, along with our collaboration groups of NASA Astrobiology Institute, University of Western Australia and Geological Survey of Western Australia.After the observation under optic and electron microscope, these cores were examined for the isotopic compositions of sulfur and carbon, and were extracted the organic compounds to examine the chemical fossils of microbes. Archean atmospheric and oceanic environment were discussed from the geochemical data. We … More also focused into paleomagnetism, assumed that geomagnetic field should play an important role to bio-activity.The obtained results have been presented at international conferences as well as domestic conferences. The number of presentation from 2002 to present have been 21 for international conferences including AbSciCon (San Francisco), IGC (Firenze) and AGU (San Francisco), and 18 for domestic conferences.One of the chief contribution of this project might shedding light on the history of development of microbes. Out results suggest that iron-bacteria and methanogen might be the dominant microbes around 3.46Ga, and the microbes might become diversified around 2.77 Ga including methanogen, methanotroph, sulfate-reducing bacteria and cyanobacteria. It also suggests that eukaryote inhabited at that era.The second is the discovery of the oldest geomagnetic field by the Earth's dinamo at 3.46 Ga.. The microbial diversity around 2.77 Ga ago could strongly relates to the increasing geomagnetic field. Less
本研究旨在了解太古宙微生物在空间和时间上的分布,了解微生物所处的地球化学环境,研究生命与环境共同进化的地球物理控制因素。2004年,我们又钻了一个洞来收集穿过Tumbiana组(2.76Ga)的岩心。在2003年的钻井项目中,我们未能获得该地层。美国研究小组(深时间钻探项目)与我们合作了今年的项目,还有我们的合作小组,美国宇航局天体生物学研究所,西澳大利亚大学和西澳大利亚地质调查局。经光学、电子显微镜观察,对岩心进行硫、碳同位素组成测定,提取有机物,研究微生物化学化石。从地球化学资料出发,讨论了太古宙大气和海洋环境。我们更多地关注古地磁,认为地磁场对生物活动起着重要作用。所取得的成果已在国际会议和国内会议上发表。2002年至今,参加国际会议(美国旧金山)、IGC(意大利佛罗伦萨)、AGU(美国旧金山)等共21次,国内会议18次。这个项目的主要贡献之一可能是揭示微生物的发展史。结果表明,在3.46Ga前后,铁菌和产甲烷菌可能是主要的微生物,在2.77 Ga前后,微生物可能变得多样化,包括产甲烷菌、产甲烷菌、硫酸盐还原菌和蓝藻。它还表明真核生物在那个时代居住。第二个是3.46 Ga的地球迪纳摩发现了最古老的地磁场。2.77 Ga前后的微生物多样性可能与地磁场增强密切相关。少
