摘要

石浦群地层的时代、沉积相是一个长期争论的问题。笔者经过两年来对该地层的工作,在其上部的灰岩中找到了多门类化石并通过对该地层9个同位素年龄样分析,确定石浦群为下白垩统,属海陆过渡相沉积。

Abstract

For a long time, there is a controversy about the age and sedimentary facies for the Shipu Group. During last two years of studies on the Formationsof the Group,the author has discovered various kinds of fossils from the limestones at the upper part of the group. Through the analysis on isotopicage date of 9 samples, it is suggested that the group is attributed to the lower Cretaceous with a transitional facies between marine-non marine.
