| Tashkurgan region in West Kunlun tectonic belt is an important tectonic transition site,it controls multiple fracture zones of geotectonic units in West Kunlun that converge here and deflect direction.The Kangxiwar fault zone is one of the most important tectonic boundary fault,the fault zone has a high degree of research in the Kangxiwar area,but the research level in the Tashkurgan region is low,and its location,structure and attributes are not clear.In this paper,using aerial remote sensing technology as the main means,ASTER and WorldView-2 high-resolution satellite data-based data sources,supplemented by regional geology,regional geophysics and field geological work,through the combination of multiple data analysis method,Xinjiang Tashi Kurgan And the tectonic framework of the Tajikistan region is divided into two parts.Through the new data geology application technology,the new situation of the Kangxiwa fault zone in the Tashkurgan region has been achieved:(1)The tectonic framework of the Tashkurgan and Tajikistan regions was established by means of remote sensing spatial images,and the extension of the Kangxiwar fault zone in the Tashkurgan region was established.The Kangxiwar fault zone from east to west through the Maier ocean,Wacha,by the Cindy along the Tashkurgan River east of Tizi Nafu near the Tashkurgan fault,then by the northwest of the city of Tucir Tigers into the Tajikistan.(2)It is further proved that the Kangxiwar fault zone is the boundary of the subduction of Paleo-Tethys ocean and it has right-handed ductile shear properties through field investigation and sample rock chemical analysis.(3)The mask-low-frequency expansion method can effectively improve the quality of remote sensing image in the shadow region.The five signs of remote sensing geological interpretation of the metamorphic zone are put forward,which is of great reference value for the use of high-resolution remote sensing data. |
