Since the Ludian M6.5 earthquake, the Zhaotong - Ludian Fault as one of the boundary faults of the Daliangshan secondary active block and the South China block, has been a great concern. The Zhaotong-Ludian Fault zone in the study area is a flower-like structural belt composed of NE、NW trending faults and broken folds. In order to have a more comprehensive and in - depth understanding of Zhaotong - Ludian fault fold belt,based on the field characteristics and stress analysis, this study has established six tectonic deformation sequences and divided six tectonic evolution stages in the four observation areas: 1) The NE and near SN fold formation stage in the middle stage of Yanshanian ；2) The Formation Stage of Zhaotong- Ludian Fault - fold Zone in the middle stage of Yanshanian；3) The Inversion of NE - trending Fault Zone in Late Yanshanian；4) Late yanshanian EW superimposed fold stage；5) Late yanshanian Zhaotong - LuDian fault zone stretching stage；6) The quaternary Zhaotong - LuDian fault zone activity stage. That provides an important geological basis for the movement study of the Sichuan-Yunnan block and the South China block after Yanshanian. Late-Pleistocene-Holocene tectonic deformation of the Zhaotong-Ludian fault resulted in both NE and NW faults.So that it forms conjugated faults. And the occurrence of the Ludian earthquake is related to NE and NW trending faults.
