民乐锰矿矿石中发现蓝藻化石六、七种,其中石囊藻细胞(Eontophysalis)和色球藻目(chroocacean)中的矿物质为钙、镁、锰的碳酸盐系列矿物。本文综合了偏光显微镜、生物显微镜、电子显微镜及X射线衍射分析,无机、有机化学分析资料,找到了蓝藻与碳酸锰矿物的密切空间关系和成生联系。引用了关于生物成矿的观点,论述本区生物形成矿物的作用过程和相关的矿物种类。提出菱锰矿形成的生物—生物化学成因的观点。
There are six or seven cyanobacteria fossils found in Minle manganese ore, of which the minerals in Eontophysalis and chroocacean are carbonate, magnesium and manganese carbonate minerals. In this paper, polarimetric microscopes, biological microscopes, electron microscopy and X-ray diffraction analysis, inorganic and organic chemical analysis of data to find the close relationship between cyanobacteria and manganese carbonate minerals and the relationship between life and birth. Cites the viewpoint of bio-mineralization and discusses the process of bio-mineral formation and the related mineral species in this area. Put forward the formation of rhodochrosite bio-bio-chemical point of view.
