The Influence of Biogenic Procession on the Accumulation and Precipiation of Silica—An example from South of Anhui and West of Zhejiang
-
摘要: 在皖南浙西分布着一条近北东向的上震旦统（皮园村组）—下寒武统（荷塘组）在硅岩条带，作者通过野外、室内的研究，对岩石的结构、构造、矿物成分各个方面进行了系统的研究，找到了放射虫壳体结构，证实了生物作用对硅岩聚集沉淀的重要意义，主元素及有机碳的分析也显示了生物作用的痕迹。Abstract: In the South of Anhui and West of Zhejiang, there is a zo ne of upper Sinian and low er Cambrian siliceous rocks w hich strech strch praximately NE.Af ter field t rip and labo ratory studies,We understood all aspects of thier tex ture and structure and mineral composi tio n and found shell of radiolarian.It is proved that biogenic procession plays an important role in the fomat ion of chert s of chert s and the analy sis of major elements shows it clearly.
