前寒武纪微古植物的研究工作,近20年来取得了很大进展,已成为前寒武纪地层研究的重要手段之一。我国在利用岩石切片方法研究前寒武纪的黑色燧石中的微体化石,在深度和广度方面都取得很大进展。然而对于早古生代燧石中的微化石研究成果目前报道还不多。 1986年作者在考察云南晋宁王家湾震旦系一寒武系界线剖面时,采集了渔户村组中谊村段的硅质岩(燧石)样品,经切片研究后,在其中3块样品中发现很多保存丰富的微化石,
The research on the Precambrian microfossils has made great progress in the past 20 years and has become one of the important means for the Precambrian stratigraphy research. In our country, the use of rock slice method to study the Precambrian black flint in the chert microfacies, both in depth and breadth have made great progress. However, there are not many reports on microfossils in Early Paleozoic chert. When examining the Sinian-Cambrian boundary line of Wangjiawan, Yunnan, in 1986, the authors collected samples of chert (chert) from the Zhongyicun section of the Fisheries Group. After slicing, three samples In the discovery of many preserved microfossils,
