Abstract:Hongshigou gold antimony deposit is located in east Kunlun metallogenic belt and Animaqing—North bayankara metallogenic subzone. Based on the analysis of oreforming geological background and geological characteristics, the oreforming background is the same as that of Dachang and Zangjingou gold deposits in the region. The orecontrolling factors are compared and analyzed, the genesis of the deposit is discussed, and the prospecting criteria are summarized. The deposit belongs to the post magmatic middle low temperature hydrothermal altered rock type. The multistage activity of the fault structure provides channels and ore hosting places for the activation, migration, enrichment and precipitation of the oreforming materials. The fault structure is the main ore controlling factor. Secondly, the deepseated magmatic activity and metamorphism of the Variscan Yanshanian period not only provide the heat source, but also bring the main oreforming materials. Magmatic activity is an indispensable condition for oreforming. The main prospecting indicators are landform, vein, color, structural fracture zone and wall rock alteration.
