摘要:Detecting the Huayin Piedmont faults and basement conditions in the Weihe Basin through magnetotelluric polaron exploration technology found that the piedmont faults in the research area are quite developed, with two stepped normal faults with larger angles, along with many small faults; From the terrestrial polarization sub-bands, it is reflected that there are many fractures in this area, and the formation energy fluctuates greatly, indicating that the energy accumulation and formation energy of the formation are discontinuous, and there is a complete anomaly of the upper and lower formation energy at a certain depth. The comparative analysis of drilling and core data believes that it is the interface between the sedimentary rock layer and the underlying Qinling piedmont basement: the overlying stratum is the Tertiary sedimentary rock,and the lower basement is the Qinling Archaean granite layer; the fault structure of the Qinling piedmont is further understood and the basement rock layer and depth also proved the accuracy and reliability of the magnetotelluric polaron exploration technology.
