Abstract This paper introduces the refineddata processing of magnetization vector inversion and Maxwell plate inversion, and takes the skarn type lead-zinc mine in Galaiaoyi area of Heilongjiang province as an example, summed up a set of data processing, analysis and interpretation of the idea that the magnetization vector inversion with the apparent resistivity profile can analyze the metallogenic environment, analysis and extraction of ore caused by abnormal, and then use Maxwell has a plate-like inversion of the abnormal lot to simulate the distribution of the orebody (low-resistance) in the ground, thus guiding the drilling and laying, and the test results in the known mining area are better.
