塔里木盆地东北缘吐格尔明背斜和阳北断裂带构造分析
Structural analysis of the Tugalming anticline and Yangbei fault in the northeastern margin of Tarim Basin,NW China
摘要
Abstract
The Tugalming anticline and Yangbei fault are located in the northern margin of the Tarim Basin and the eastern part of the Kuqa fold thrust belt in front of the South Tianshan Mountains.Both of them are basement-involved structures.Yangbei fault is an inverted structure.Its deformation history can be traced back to the Jurassic-Cretaceous normal faulting.The Cenozoic tectonic inversion and accelerated thrust deformation occurred at the end of Cretaceous to the beginning of Paleogene,the end of Paleogene to the beginning of Neogene,the Early Miocene,Pliocene and Quaternary.The Tugalming anticlinal structural belt is a secondary basement involved structural belt derived from the Early Miocene and later thrusts of the Yangbei fault.It is composed of the Tugalming anticline and the two thrust faults in its north and south.Proterozoic metamorphic rocks in the anticlinal core are exposed.The Meso-Cenozoic is directly unconformably overlying on the metamorphic rocks,and the whole Paleozoic is missing,which indicates that the study area may belong to a long-term Paleozoic paleouplift.关键词
