Abstract: Based on the studies of the geology and geochemistry of typical gold deposits, as well as the distribution and genesis of gold deposits and occurrences in the Duobaoshan area of Heilongjiang Province, the gold metallogenic rule is analyzed. The results show that the gold mineralization is controlled by NW- and NE-trending faults, of which the NEtrending faults are dominated. From west to east, the gold mineralization is becoming stronger. The ore bodies are hosted in the Middle Ordovician and Early Yanshanian volcanic rocks, with ore-forming materials from mainly Yanshanian magmatic rocks and wallrocks. The ore-forming fluids are mainly from meteoric water. The homogenization temperature of fluid inclusions ranges from 133℃ to 267℃. The genesis of the gold deposits in the area belongs to typical epimesothermal ore deposit. At last, some prospecting criteria are proposed for the further exploration in the area and the prospecting orientations are determined.
