摘要
本文从构造地质角度研究盆地泥岩粘土矿物的分布和演化,认为构造背景和构造运动是控制盆地泥岩粘土矿物的根本因素,较合理地解释了中国东、西部含油气盆地泥岩粘土矿物组成特征的差别及西部第三系泥岩中普遍存在的一种特殊粘土矿物组合(泥岩的粘土矿物主要由伊利石和绿泥石组成,但成岩程度很差)。
The paper discusses the clay mineral distribution and evolution of argillaceous rock in sedimentary basins from view of tectonic geology.It's considered that tectonic backgrounds and movements are the basical factors controlling clay minerals of argillaceous rocks in sedimentary basins.This explains more reasonably the differences of clay mineral compositional characteristics of argillaceous rocks between petroleum basins in the east and west China.Furthermore,it explains a special kind of clay mineral assemblage generally existed in western Tertiary argillaceous rocks,in which the clay minerals are mainly composed of illite and chlorite but the diagenetic grade is very low.
