Abstract: Daping gold deposit is one of the typical deposits in the Ailaoshan metallogenic belt，it is regarded as the vein-type gold poly-metallic sulfide deposit that is commonly developed in close association with the product of collision orogenic environment.In order to analyze the deposit genesis types of the Daping gold deposit in Yuanyang county,Yuannan province,based on the regional metallogenic background and the geological exploration results of the Daping gold deposit in Yuanyang county,Yunnan province,the typical deposit geological characteristics,mineral assemblage characteristics and wall rock alteration characteristics are discussed in depth,the metallogenic period is divided,besides that,the basic research results of the ore-forming materials and ore-controlling tectonic characteristics are also analyzed in detail.The results show that:①the gold deposit is controlled by sinistral strike-slipping shear,the main ore-bodies are developed in the transition part of tense-compression shearing space.②the metallogenic material source is varied,they are affected by multi-phase tectonic mineralization and superposition reconstructed by poly-genetic thermal fluid combination,so,the Daping gold deposit in Yuanyang county,Yunnan province is a vein-type poly-mental deposit with middle temperature.Based on the above research results,the prospecting indicators and prospecting direction in the mining area are discussed,the result show that the prospecting work in the mining area should be conducted in the area where the alkali-rich porphyry is developed and tectonic activities superposition,the key prospecting portion is the area where the lamprophyre and granite porphyry are exposed,in addition,the poly-metallic sulfide enrichment places should also be paid attention.The above research results can provide reference for the further deep prospecting and prediction in the mining area.
