古热水成矿区特殊生物群研究

The research of hydrothermal process is one of important fields of geoscience. The community discoveried around the hydrothermal vent in the deep seafloor has caused that scientists considered the origin and evolution of life.At the same time, the research of hydrothermal biology has become the hottest field in hydrothermal process.The project studies the special biota in ancient.hydrothermal metallogenic province and discusses the existing form of life in extreme environment forming ore by investigating the speciality of ecological system in metallic sulfide in ancient hydrothermal environment. The significance includes that : ① it.provides comparable information for morden hydrothermal biology, and.offers new material and content about the origin and evolution of life in more long time span. ② it affords distinguishing signs of biology in ancient hydrothermal environment. ③ it can consummate the research of the palaeobiology in abnormal hydrothermal.environment. ④ it can develop the theory of biomineralization.

通过对秦岭典型热水沉积矿床中宏观生物群落、化石地球化学以及古热水生态系与成矿元素关系的研究，结合与正常沉积环境中的生物群的对比，探讨古热水成矿环境生物群的特殊性，为现代海底热液生物学的研究提供可比性的重要信息，为生命起源及演化的研究提供新材料，为古热水沉积成矿环境提供生物学的判别标志，发展和完善生物成矿理论。
