Numerical Simulation Research on the Identification of Geological Body Boundaries in Sandstone-type Uranium Deposits Using Magnetotelluric Data
With the increasing demand for resource development and utilization,the requirement for the accuracy of geophysical detection data identification is also growing.In this paper,several typical models were established to carry out research on the identification of target boundaries.The tipper response data and single-point inversion resistivity curve processing were utilized,and the horizontal gradient method,analytical signal method,and Theta Map method commonly used in gravity and magnetic data processing were integrated into the inversion results of magnetotelluric data.Through comparative analysis,it was found that the tipper data can better identify the lateral boundaries,the derivative method has great guiding significance for the longitudinal top and bottom interfaces,and the Theta Map method can better identify the boundaries of underground media.However,the processing methods should be carefully selected based on actual geological conditions.This research provided an ideas for subsequent practical applications of boundary enhancement.
