摘　　要：哈达门沟金矿区处于华北克拉通北缘中西段,为区域内典型大型金矿床。通过对构造控矿特征、矿脉分布及矿化富集特征等进行分析研究,认为山前钾化带为山前断裂派生的次级构造,是矿区内重要的控矿构造。矿脉呈向西发散、向东收敛的特征,越靠近山前断裂,构造越发育,矿脉越密集;哈达门沟金矿区东部哈达门沟矿段剥蚀相对较浅,靠近山前钾化带导矿构造地段具有较好的找矿潜力,控制程度较低的矿脉深部及空白区平行盲矿脉为重点找矿方向,山前钾化带深部及其与矿脉交汇部位可能为矿化富集部位。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.

关 键 词：山前断裂 剥蚀 盲矿脉 钾化带 哈达门沟金矿区
