APPLICATION OF REMOTE SENSING TECHNIQUE IN THE MAPPING OF CENOZOIC GEOLOGY OF THE EAST KUNLUN MOUNTAINS
-
摘要: 利用不同地质体在同一波段或相同地质体在不同波段具有不同色调的变化规律，对东昆仑东温泉盆地的ETM图像进行了详细地质解译，建立了新生代地层和新构造的解译标志。解译结果表明，在遥感图像上可以准确勾绘新生代地层的界线和确定新生代断裂位置。通过野外地质验证将新生代地层划分为10个填图单位，新生代断裂主要有近东西向的左旋走滑断裂和近北西西向的逆冲推覆构造。遥感地质解译和野外验证结果对比表明，多光谱遥感影像在新生代地质填图中可以发挥重要作用。Abstract: According to the color variations of different geological bodies in the same wave band or the same geological body in different wave bands, a close geological interpretation has been made for the ETM images from the East Wenquan Basin of the east Kunlun Mountains, resulting in the establishment of interpretation makers for the Cenozoic strata and new structures. The interpretation allows us to accurately define the Cenozoic strata boundaries and Cenozoic fault locations on the ETM images. The Cenozoic strata in the mapping area can be divided into 10 mapping units based on the field survey. The Cenozoic faults include nearly NW left-lateral strike-slip faults and nearly NWW thrust nappe structures. It is believed that multispectral remote sensing image can play an important role in Cenozoic geological mapping.
