Abstract: Hadamengou Gold District lies on the middle west section of North China Craton and belongs to typical large-scale gold deposit in the area.Based on the study and analysis of structural ore-controlling characteristics,ore vein distribution and mineralization enrichment characteristics,it takes that the Shanqian potassic belt is the secondary structure derived from Shanqian fault,and important ore-controlling structure in the district.The ore veins diverge to the west and converge to the east,the closer to the Shanqian fault,the more developed the structure is and the more concentrated the ore veins are; the denudation of Hadamengou ore section in the east of Hadamengou Gold District is relatively shallow.The ore-conducting section close to the Shanqian potassic belt has good prospecting potentials.The deep parts of ore veins less controlled and the parallel blind ore veins in the blank area are important prospecting directions,while the deep parts of Shanqian potassic belt and its convergence section with ore veins can be mineralization spots.
