Abstract: In order to further prove the ore-controlling structure and prospecting direction of Zhesang Gold Deposit in Yunnan Province，the ore-controlling structural feature and geological characteristics are analyzed based on the outdoor investigation.According to the analysis results，there are three main types of ore-controlling structure in Zhesang gold deposit：NE-trending faults，secondary folds and contact zone.These ore-controlling structures provide heat，driving force，migration pathways and enrichment space for the reformation of gold deposit in the area.The mining area has experienced several tectonic evolutions，such as Caledonian movement，Indosinian movement and Yanshan-Himalayan tectonic activity.These make the controlling structures with multi-stage activity and the ore-forming elements activated repeatedly.So the superimposed mineralization becomes the typical feature of Zhesang gold deposit.According to the characteristics of the ore-controlling structure，the fault zone，secondary folds swell band，contact zone and parallel with NE-trending fault should be focused in further prospecting work.In particular，the secondary fragmentation of quartz is the fine sign of mineralization.
