Permian Sedimentary Characteristics and Evolution of Paleo-environment in the Qiaer-long,Akto County,Xinjiang

LI Wen-jie1,CUI Chun-long1,2(1.School of Environmental Resources and Engineering,Southwest University of Science and Technology,Mianyang 621010,Sichuan,China; 2.School of Civil Engineering and Architecture,Southewest University of Science and Technology,Mianyang 621010,Sichuan,China)  
Based on measured section and geological mapping data,the authors believe that the Permian strata is typical of a flysch formation of terrigenous clastic with carbonate construction.There is mainly turbidite sedimentary basin at Qiaer-long zone,basin sedimentary has three kinds of sedimentary facies-forcontinenta,littoral-neritic facies and abyssal facies.Evolution of the Permian paleo-environment can be divided into the early Delta-Coastal-shallow turbidite sedimentary basin,medium-Marina-shallow mesa slope turbidite and the late stages.Permian clastic sedimentary basin is dominated by near-shore turbidity circumstances,and from the Carboniferous strata of the limestone blocks piled up in the mix on the horizon gradually from south to north elevation,huge rock block.The distribution also has changed gradually from south to north,the trend of smaller and fewer.This is undoubtedly in the Carboniferous and Permian crustal movement between the time a major geological events,during which the latter part of reform should be destroyed once the event interface exists.
