Abstract:In order to ascertain the metallogenic geological background of the huge coverage areas in Eastern Guizhou, and based on the 1:50 000 aeromagnetic data in 2014 and the data of geology and gravity, the authors studied the aeromagnetic features of different magmatic rocks and structure units in the study area. And the region structure map was completed based on comprehensive analysis. Through comparison and analysis, seven new intrusive rocks, fifteen altered rocks and seventeen faults with different scales were outlined. The results are of great significance for the study of basic geology and ore prospecting in Eastern Guizhou.
