Abstract
A method and a system for predicting an occurrence depth of a weathering crust-type rare earth deposit orebody are provided. The method includes: performing field test on a weathering crust by using a high-density electrical method; performing computational inversion on test results to obtain apparent resistivity data of the weathering crust at different depths; and correcting a distortion value of the apparent resistivity data due to terrain fluctuations based on a terrain of the weathering crust, obtaining apparent resistivity data of the weathering crust after terrain correction at different depths by using a ratio method, further obtaining a first-order derivative curve of the apparent resistivity versus depth changes, and determining the occurrence depth of the rare earth orebody by combining parameters of a logistic regression model.
