Abstract: Shapinggou exploration area is located in north Huaiyang metallogenic belt in Anhui, which is the main concentration area of molybdenum lead zinc polymetallic mineralization in west Anhui Province. Dozens of Pb-Zn deposits have been found in the study area,mainly small deposits and lack of systematic research and summary data. In order to determine the relationship between Pb-Zn deposits and the ore-forming geological bodies as well as the types and properties of ore-forming structures and structural planes, the authors summarized the characteristics of mineralization,so as to guide the prospecting prediction. A study was carried out on the "Trinity" metallogenic characteristics of typical deposits in this area. The results show that there are four types of Pb-Zn mineralization: Breccia type, skarn type, structural alteration type, and hydrothermal vein type. The ore-forming geological bodies are of the Late Yanshan intermediate acid magmatic rock, and the ore-forming structures are the intersections intersections of the NE and NW fault structures. The ore-forming structural planes are mainly NE and NW fault structural planes, breccia tube, interlayer fracture zone, and contact zone, etc. Based on the metallogenic characteristics of lead-zinc deposits and the elements for ore prospecting prediction, the geological model for ore prospecting prediction of lead-zinc deposits is established in order to evaluate the ore prospecting potential in this area.

Key words: Shapinggou, trinity, Pb-Zn deposit, metallogenic model
