Shuidonggou gold deposit in Tianshui City is located in the southern side of the great reversed "S" type structure in the junction area of Caledonian orogenic belt of Qilian and northern Qinling, where gold mineralization is controlled strictly by EW-striking fractures. The walk-rock alteration is characterized by silicification, limonitization, pyritization and sericitization. The gold-bearing minerals mainly are limonite, pyrite and arsenopyrite. The results show that the basic conditions of deposit formation include meta-sandstone, ductile-brittle fractures and intermediate-acid intrusive rock, the EW-striking tectonic alteration zone and the areas where geochemical anomalies have been recognized are the favorite for prospecting gold.
