TECTONIC EVOLUTION OF THE SEDIMENTARY BASINS IN WESTERN LIAONING PROVINCE AND THEIR GENESIS TYPE

摘要: 辽宁省西部地区发育了一系列中生代小型含煤盆地。这些盆地内有广泛的油气显示,但勘探效果却不理想。本文分析了辽西地区地球动力学背景,结合地球物理勘探资料研究了辽西地区盆地构造几何学和运动学特征,探讨了辽西地区构造演化史、盆地形成机制和成因类型,并以阜新盆地为例,阐述了盆地的构造特征和圈闭类型。

Abstract: There are several small Mesozoic coal basins in western Liaoning province.Those basins are also petroleum basins.This paper is a research report of the formation and evolution of the basins.Firstly,geodynamic background of western Liaoning province is studied.Secondly,structural geometry and kinematics of these basins are analyzed based on seismic and magmatic data.Thirdly,the mechanism of formation of the basins and their genesis are discussed.Finally,structural features and trap types of the basin are illustrated by an example.
