摘要

四川盆地的上三迭统

是一套以陆相为主的兼有海相、海陆交互相碎屑岩沉积。岩性、岩相变化较大

缺乏区域性标志层。上三迭统内部的地壳运动界面(简称运动面

下同)

常被特有的底冲刷现象所混淆和掩盖。以 Clathropteris—Dictyophyllum 为代表的植物化石组合

自下而上分异不甚明显

而赖以建组划段的菊石、海相瓣鳃类的赋存和分布，则明显地受到沉积环境的影响。故在地层的划分对比上，历来各循其是，意见纷纭。

Abstract

Stratigraphical correlation and classification of the Upper Triassic of Sichuan Basin have been worked out here in the light of crustal mo-vement planes

sedimentation cycles

paleontological data and litho-facies analysis with consideration of the local lithological reference hori-zons.
