粤西冻水坑发现晚元古代微古植物化石

THE DISCOVERY OF LATE PROTEROZOIC MICROFSSIL PLANTS IN DONGSHUIKENG,WESTERN GUANGDONG

摘要: 微古植物化石产于云开群中亚群中段上部的灰色条带状硅质岩中,共计15属30种。笔者推论广泛分布于粤西的云开群,其时代不应仅限于震旦纪,其中还应包含有青白口纪甚至更老的地层。

Abstract: Microfossil plants occur in gray banded siliceous rocks in the upper part of the middle member of the middle subgroup of the Yunkai Group.There are a total of 15 genera and 30 species.The author infers that the Yunkai Group widespread in western Guangdong should not be confined to the Sinian but also comprise the Qingoaikou Period or even still older strata.
