摘要
结合地质找矿工作实践,选取四川麦架沟铜多金属矿为研究对象,通过收集、研究前人区域地质调查、矿产勘查成果,在总结区域地质背景和勘查区地质特征的基础上,对铜多金属矿的成矿地质条件进行研究。认为该矿的赋矿地层为三叠系博峪河组一段,岩性为变质细砂岩与板岩互层,铜、金矿(化)体受控于中寨向斜西翼顺层分布的层间破碎带,呈透镜状、不规则状产出。矿石以细粒粒状结构、细脉浸染状构造为主,有用组分为黄铜矿、黄铁矿及自然金,矿床成因类型属热液充填脉型铜、金矿床。
Combined with the practice of geological prospecting,Sichuan Maijiagou copper polymetallic ore was selected as the research object.Through the collection and study of previous regional geological survey and mineral exploration results,the regional geological background and the geological characteristics of the exploration area Think the ore formation of Triassic Po valley river group section,lithology for metamorphic fine sandstone,slate,copper polymetallic ore(chemical)is controlled in the village of layers,lens,irregular output,ore mainly fine granular structure,fine pulse immersion structure,useful components for chalcopyrite,pyrite and natural gold,deposit formation type is hydrothermal flling vein type copper,gold deposit.
