Abstract: Abstract：In view of the complex structure background in Luoping area, the authors studied the tectonic framework of this area, with the purpose of revealing the tectonic evolution in the northern part of the Mile-Shizong fault. The characteristics of remote sensing technology were used to interpret and identify the faults macroscopically. Through field survey, the image features of the faults were acquired. On the basis of the density analysis of the faults, the detailed fault characteristics were studied from the viewpoint of geological and topographic features. The results show that the NE-trending fault belt in Luoping is the northern extension of the Mile-Shizong fault. This belt has controlled sedimentary and tectonic evolution since the Triassic in Luoping, with the development of different features on the two sides of the fault belt.
