In this paper, based on the test data of Quernese basin in northern Guangdong, based on the shading (gray scale) feature information and the pseudo-color density segmentation value of the patch, the mathematical geology method is used to explore the ore prospecting information in the lead-zinc mineral area. The image of ERT S-2 satellite was scanned on December 24, 1975 with the serial number of 132-44, that is, the geologic group of Shaoguan amplitude data station of Guangdong Province passed PHOSDA C-1200 digital color image analyzer 1 500 000 MS S 5 and MS S 7 Wei films, according to the unit cell grid to measure the false color density of each gray scale (density value lg projected luminous flux transmitted light flux in the selected area to 4 × 4 km ~ 2 Of squares (total 100
