库车冲断带新构造遥感分析

库车坳陷区在新生代产生一系列向盆地逆冲的冲断构造，这些构造在遥感图象上表现明显。通过对区内４景ＴＭ数据数字镶嵌，编制了研究区岩性地层解译樗表并以此对全区进行了解译。根据遥感影象特征分析了该区的褶皱断裂构造分布，确定了库车县北部、喀拉玉尔滚区、库独公路段的各个新生代晚期背斜构客相关断层的空间分布，以及相应的次级剪切面构造。从第四纪沉积物、冲积物以及沟系的影象中撮相关构造信息，分析浅覆盖物下地质体界面

Neotectonic Analysis of the Kuqa Foreland Thrust Belt by Using Remote Sensing Data

A series of thrust structures developed in the Kuqa depression during the Cenozoic are clearly shown on the remote sensing images. A mosaic image consisting of four scenes of TM data was analyzed and interpreted for the Kuqa foreland basin. The distributions of folds and faults are analyzed using remote sensing data. The late Cenozoic anticlines, distributions of related faults and second-order shear structures of three sub-areas, the northern Kuqa County, the Kalayuergun sub-area and the Kuqa-Dushanzi Highway sub-area, are identified. The information of subsurface geological body interface is extracted from the TM images of the Quaternary sediments, alluvium and gully. Based on this information, the characteristics of neotectonic movements of the Yangxia buried fault and Yaken growth anticline in this area are identified.
