摘　　要：美河金矿是松潘-甘孜成矿省内一处典型构造控矿石英脉型金矿,属造山型金矿。为理清矿床成矿规律以指导深部及外围找矿,本文根据野外地质填图和大量的钻孔、坑道等探矿工程资料,运用构造解析等方法,对构造格架和构造控矿期次进行了分析,探讨矿床成因,并对与成矿物质来源相关岩体进行了区域对比研究,认为在矿区以北分布的酸性岩体与深大断裂之次级断裂的叠合部位,是下次找矿工作的重点靶区。Meihe gold deposit is a typical structural ore controlling quartz vein type gold deposit in Songpan-Ganzi mineralization province,which belongs to orogenic type gold deposit.To clarify deposit metallogenic regularity in deep and periphery prospecting,based on the field geological mapping and large amount of exploration engineering data,such as drilling,tunnel using the method of structural analysis,the time of tectonic framework and tectonic ore-controlling was analyzed,and the ore deposit genesis,and study rock mass in the north of mining area which related the source of ore-forming materials,which believes that the main point is the next prospecting target areas.where is the acidic rock mass and the deep fault secondary fracture composite parts.
