摘　　要：本文着重研究了扬子地台北缘上震旦统陡山沱组、灯影组及下寒武统下部岩家河段的微古植物组合特征。初步建立了Ⅰ、Ⅱ两个微古植物组合，分别与陡山沱村阶和灯影峡阶相对应，分析了微古植物组合在地层划分与对比及在震旦系－寒武系界线的划分上所起的作用。The characteristics of micropaleoflora are studied from the Doushantuo and Dengying Formations (LateSinian) in the northern margin of Yangtze platform.The two assemlages of micropaleoflora (Ⅰ,Ⅱ ) corresponding to the Deushantuo - Dengying stage are constructed. The authors also studied the role of micropaleoflora to the boundary between Sinian and Cambrian systems and the stratigraphic classification correlationwith those of neighbouring area and abroad.
