| 摘 要： | 通过对武当山推覆体东部武当山群杨坪组进行较深入的地层学研究,认为杨坪组与下伏挡鱼河组应分属不同构造层,其间可能缺失青白口系—下震旦统的沉积记录;杨坪组微古植物组合特征显示出晚震旦世—早古生代早期的时代面貌。

| Abstract: | On the basis of an intensive stratigraphic study of the Yangping Formation belonging to the Wudangshan Group in this area. It is considered that the Yangping Formation differs from the underlying Dangyuhe Formation in tectonostrata, and that the deposit from Qingbaikou system to Lower Sinian between the two formations are absent. Micropaleofloras assemblage of the Yangping Formation reveals the age of late Sinian to early Palaeozoic. It is of an important significance for us to recognize the evolution of paleotectonics and paleogeography of Precambrian in this region. |
