The gold deposit in Dadonggou area of Gaizhou City, Liaoning Province is in the middle of the FenshuiHuatong gold and polymetallic metallogenic belt. The genesis of the deposit belongs to sedimentary metamorphismhydrothermal alteration. In the middle of the exploration area, the results of the previous geochemical exploration were used to circle 8 Au anomalous areas and 7 magnetic anomaly areas. The superimposed areas of the two were mainly located in Dazibao-Shaheshanggou area, which were generally distributed in the northwest direction. It has a large area and has a good prospecting prospect, and it has good compatibility with gold-bearing structural altered rocks. The main ore minerals in the ore are pyrite,Marcasite, pyrrhotite, a small amount of arsenopyrite and trace amounts of chalcopyrite. The state of gold minerals is distributed in three states: inclusion gold, intergranular gold and fissure gold.
