近年来,刘鸿尤、沙庆安等在研究中国南方震旦系的工作中,先后从滇东及鄂西采回了一些标本,经笔者分析含有不少孢子及植物残体化石。研究材料系1962年采自滇东宜良螺絲塘、鄂西秭归冀家湾及宜昌秋千坪等地的震旦系。含化石标本的地层,均属上震旦统。样品的分析,基本上按格里丘克法进行,重液应用ПД-6,分析后的样品粘成固定薄片作显微镜下观察。分析鉴定后的初步结果是,从鄂西上震旦统灯影组及陡山沱组的白云岩和黑色页岩的六块标本中,
In recent years, Liu Hongyou, Sha Qing’an, etc. studied some Sinian lines in southern China and retrieved some specimens successively from eastern Yunnan and western Hubei. After analyzing some spores and plant residual fossils, Liu Hongyou et al. The research materials were collected from the Sinian screwtang in 1962 in Yunnan Province, the Jiaji Bay in western Hubei Province and the Qiuqianping site in Yichang. Fossil specimens containing the strata, are on the Sinian. The analysis of the sample was performed basically by the Glicuch method. The heavy liquid was applied to the ПД-6, and the analyzed sample was observed as a sticky fixed sheet under a microscope. The preliminary results of the analysis and identification are as follows: From the six samples of the Upper Sinian Dengying Formation and the Doushantuo Formation dolomite and black shale,
