塔里木盆地北部断裂格架分析

通过对塔北６条区域性主干断理解力学性质及发育历史的分析，论述了控制本区构造变形的基本断裂格局，认为：（１）分地北缘南天山和西南缘昆仑山两板块边缘活动产生的挤压应力在塔联合和叠加，造成了该区现今“南北分带、东西分块”的构造格局，（２）挤压应力是塔北构造变形的主导应力，海西－印支期ＮＥＥ和ＮＷ向两组区域断裂分别平行于两板块边缘，均属压性逆冲断裂，平移分量极小，ＮＷ向断理解主体不是扭断裂，只是喜山期叠加

STRUCTURAL FRAMEWORK OF MAJOR FAULTS IN NORTHERN TARIM BASIN, XINJIANG

Based on the analysis of kinematics and dynamics of six major faults in Northern Tarim basin,the regional tectonic environment of the structural deformation in the area is discussed in this paper.The main conclusions obtained from the studies are as follows:(1) regional compression is a basic property of structural deformation in the Northern Tarim basin,which was controlled by Tarim plate convergence in northern and southwestern margins;(2)the characteristics of structural deformation change regularly from north to south, and from east to west part of the studied area: and (3)besides the deformation caused by the regional compression,the detachment of different levels also strengthens the deformation of structures.
