摘要

本文根据对安徽南陵麻桥、安庆月山、南京安基村剖面对比、分析

认为角砾岩段、杂色过渡层、紫红色砂页岩段连续渐变

角砾岩段应是黄马青群的真正底界。根据角砾岩的组构特征、物质成分及其与下伏青龙群的接触关系、上下构造特点

认为作为印支运动的主要幕—金子运动是存在的。

Abstract

Through the observation of the profiles at Maqiao in Nanling

Yueshan inAnqing and Anjicun in Nanjing

the member of breccia

variegated shale and purple sand-shale are found to be successive sedimentation. Their occurrences coincide with each other and discord with underlying Qinglong Group. So the authors suggest that the breccia member should be the basal boundary of the Huangmaqing Group. According to the texture and composition of the breccia member and the differentia between upper and lower structures and their un-comfornity

we consider that Jinzi Movement

the main episode of the Indo-sinian Movement

is a presence.
