Abstract: Geological characteristics and metallogenic mechanism of Habuchuri Pb-Zn-Ag deposit are analyzed.The study results show that:①Habuchuri deposit is a small porphyry-skarn-hydrothermal medium-low temperature Pb-Zn-Ag deposit in Inner Mongolia;②the formation of ore-bodies are significantly affected by the structures,and the main ore-controlling structures are mainly for the NNE structural belt and the NW and NE brittle faults in the Weiner River area;③the mineralization period of the deposit is Yanshanian,Yanshanian intermediate-acid small rocks are the main source of heat and materials in the area,they intruded into the favorable structural parts for many times and metasomatism occurred with the "silica-calcium surface" of arkose,siltstone and calcareous siltstone in hongshuiquan formation of the surrounding rock and enriched the ore;④the geochemical anomalies in the area are good indicators of ore-bodies,pyritization,silicification and skarnization are closely related to mineralization.The above research results can provide reliable reference to further expand the prospecting prospect in this area.
