Abstract

The present invention provides a geological data analysis and modeling method, comprising the following steps: ①Qualitative analysis: for the processed audio magnetotelluric sounding data, use two-dimensional deviation analysis, electrical main axis feature analysis, and polarization feature analysis respectively , Magnetic induction vector feature analysis and quasi-section map feature analysis are analyzed in at least three ways to obtain geological section data; ②AMT inversion: perform nonlinear conjugate gradient NLCG two-dimensional inversion on geological section data; ③Model establishment: according to the above According to the obtained data, according to the principle of continuous drilling, geological profile, lithology data and resistivity contour line, the section is electrically stratified. Combined to establish a geological and geophysical prospecting model. The beneficial effect of the invention is that: through qualitative analysis, AMT inversion and model building, a set of analytical methods with strong applicability, easy operation and system are provided for geological exploration of ore deposits.

Description

technical field [0001] The invention relates to a geological data analysis modeling method.
