| 摘 要： | 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。

| Abstract: | More than six species of Cyanophyceae fossils were found in manganeseore from Mingle,west Hunan.The ore-forming materials in the cells of Eoen-tophysalis are Ca-Mg-Mn minerals of the carbonate series.Based on the dataobtained from polarizing microscopic,biomicroscopic,micropropic,X-diffrac-tion,and organic and inorganic chemical analyses,close spacial and geneticrelations have been established between Cyanophyceae and manganocarbonateminerals.From the biominerogenetic point of view we describe the biominera-logical process and relevant minerals.It is proposed that rhodochrosite is ofbiological-biochemical genesis. |
