Abstract: The regional metallogenic geological conditions of Xiaopengjiang Pb-Zn-Ag deposit is good, but the geological working degree is low in the past.In order to conduct systematic evaluation of the prospecting prospect of mining area,the geological characteristics,orecontrolling conditions,prospecting criteria and metallogenic regularity are analyzed and studied,and the prospecting prospect is evaluated.The study results shows that:①Xiaopengjiang Pb-Zn-Ag deposit belongs to the magmatic hydrothermal filling metasomatic Pb-Zn polymetallic deposit,the veins are grouped and grouped in the inner contact zone of the west of the Jinjiling rock mass, controlled by the secondary fracture zone of the regional ore controlling fracture F₁ and F₂;②inner contact zone of rock mass,ore-controlling fault and its secondary fault,alteration such as greisenization and old holes formed by people mining can be taken as the favorable prospecting criterias of the mining area;③the northward vein in the mining area has a stable trend along the direction and tendency,and the deep part has the possibility to expand the prospect;④the metallogenic conditions is good, the element anomalies are well developed, and the mineralization is obvious,therefore,the prospecting prospect of the mining area is good,it is necessary to conduct further mineral exploration work.
