Abstract： Yunxi County is rich in metal mineral resources with relatively concentrated mineral distribution. By analyzing the geological characteristics of Shuitian Gold Deposit in Yunxi County， the deposit genesis is clarified in this paper. Research has shown that the main ore-bearing strata are the Devonian Tieshan Formation （D3t）， with the main ore-controlling fault being a northeast trending fault， and the natural type of ore is mainly cataclastic altered rock type， belonging to a fine-grained disseminated gold deposit of medium to low temperature hydrothermal origin.

Keywords： gold deposit; geological characteristics; metallogenic stage
