新疆准噶尔含煤盆地基本构造格架与认识
Fundamental Structural Framwork and Cognition of Junggar Coal Basin,Xinjiang
摘要
Abstract
Based on comprehensive analysis of the structure and coal hosting features in coal fields,in addition analysis of the typical structural profiles in the northwest、northeast、east and south of Junggar Basin, ascertained the basic structural pattern as follows:Firstly,the existing tectonic framework of Junggar Basin was finalized during the middle to late period of Himalayan movement.Chronically in the nealy south-north compress stress field,showing alternating depressions and uplifts、belts in S-N and blocks in E-W in general;Secondly,intense structral deformation around the basin margin but gradually weak and shallow in the center,showing concentric-ring shape structure on the whole,revealing the dynamical、kinematical and geometrical features controlled by orogenic belts around the basin and stress field from edge to inside;Thirdly,the large-scale coal accumulation occurred in the extension/weak compress tectonic stress field during early-middle Jurassic epoch;Fourthly,the thrust belts around the basin maybe the potential prospective areas for coal resource exploration and exploitation.关键词
