Abstract: The distribution law of minerals mainly includes spatial distribution, time distribution, symbiotic relationship and internal genesis, which are closely related to the occurrence and development of various geological conditions. In this paper, a comprehensive study was carried out on the geological conditions such as tectonic background, strata, magmatic rocks and structures, and the distribution characteristics of discovered deposits （ mineralization points ） in the Dachechang-Amenshangde Area of Alxa Right Banner, Inner Mongolia. In the study area, two grade I metallogenic prospect areas and three grade II metallogenic prospect areas were divided, two class B prospecting target areas and one class C prospecting target area were delineated, and the metallogenic potential of each metallogenic prospect area was further evaluated, aiming to provide some suggestions for future generations to carry out mineral exploration in this area.
