Segmentation of the Longmenshan Fracture Zone Based on Deep Electrical Structural Characteristics

The strike variability of the Longmenshan Fracture Zone has long been noted by many scholars, but has rarely been specifically discussed. These differences are mainly manifested in the nature and spread of the basement, stratigraphic development characteristics and evolution history, tectonic deformation characteristics, subsidence and uplift characteristics, and active tectonics. Through a large amount of data investigation, it can be seen that the Longmenshan area, as a research hotspot in the tectonic region of the Qinghai-Tibetan Plateau, has carried out a large amount of geological exploration around its deep crustal movement, rock body rheological mechanism and the geological structure of the large region, etc.. However, geophysical analyses of the segmentation of the Longmenshan Mountain are mostly focused on the petroleum sector of seismic, heavy magnetic and other data, and there are very few magnetotelluric sounding to form a model for the deep electrical structure to optimize its data multi-resolution. to optimize the multi-resolution of its data. In this paper, we use geophysical means to identify the deep geological structure of the Longmenshan Mountains, adopt a comprehensive evaluation method to suggest the regional tectonic background, geotectonic conditions, regional geologic conditions, engineering geologic conditions, metallogenic conditions, etc., and conduct a study on the seismicity caused by different parts of the Longmenshan Fracture Zone. Research on seismic activities caused by different parts of the Longmenshan Fracture Zone.
