Title: Research of Cenozoic structural deformation in southeastern Tarim basin,northwest China.
Abstract: It is very important to study the Cenozoic deformation of Southeatern Tarim basin,which helps discussing the Cenozoic characteritics of Atlyn Tagh tectonic belt and the relationship between West Kunlun tectonic belt and Altyn Tagh tectonic belt. Combining with geophysical and sedimentlogical data,it discussed the characteristics and spatio-temporal variation of the Cenozoic structural deformations of the Southeastern Tarim.The deformations of the Southeastern Tarim are controlled by West Kunlun tectonic belt,Altyn tectonic belt and Cherchen strike-slip falut belt.The starting time of the deformations becomes earlier from north to south. In the southwest part,the deformation style shows as thrust structure which is controlled by the northward thrusting of West Kunlun tectonic belt.and in the southeast part,the deformation style shows as strik-slip thrsut structure which is controlled by the Altyn Tagh Fault strike-sliping;while in the north part,the deformation style shows as basement involved strik-slip thrsut structure which is controlled by the Cherchen fault strike-sliping.The basin in Minfeng area began to flex and subside due to the West Kunlun tectonic belt thrusted on a large scale,while the Cherchen fault show weak activity during Miocene.The deformations were spread all over the southeatern Tarim basin during Pliocene.The thrust and slip of the West Kunlun and the Cherchen had greatly strengthened up,at the same time,the slipping of Altyn fault zone was violent.Therefore,sub-faults strongly thrusting-sliping at north side of Altyn Tagh Fault zone and the basin in Ruoqiang area was shaped.The thrust of West Kunlun tectonic belt is earlier than the slip of Altyn Tagh tectonic belt.So the slipping of later reworked the thrust deformation of West Kunlun.
