Four major faults and six secondary faults have been identified according to the horizontal fault position information provided by the first four methods, and the fault depth information were obtained using the Euler deconvolution method. The interpreted faults were identified as the main basin-controlling structures in the study area, which was helpful for deepening the understanding of the basin's structure, as well as providing important references for delineating hidden polymetallic ore veins.展开更多
