摘要

苏北金湖凹陷北部

包括三个次一级构造单元

即三河次凹陷、刘庄构造带和唐港构造带(图1)。该区处于东台坳陷与建湖隆起两大构造单元的过渡地带

新生代沉积变化较大

相变与地层缺失现象错综复杂。本文所研究的早第三纪晚期—晚第三纪沉积

即三垛组二段(简称“垛二段”)—盐城组二段(简称“盐二段”)尤其如此。

Abstract

The north section of Jinhu seg occurs in zone of transition between Dun-tai depression and Jianhu uplift.Cenozoic sediments vary greatly.Parts ofthese sediments show no distinct lithological and electrical properties.Analyses of 110 samples of heavy minerals are given and used as criter-ian for stratigraphical division and correlation on the basis of their as sembl-ages

typomorphic peculiarities and differences in distribution in various rockhorizons.
