摘要
马关县铜厂坡铜矿位于老君山锡锌多金属成矿区的北西段,该矿区矿体与区内岩浆活动、构造、围岩岩性等关系密切,其中寒武统田蓬组上段的大理岩化白云质灰岩夹片岩为赋矿层位。层间滑移断裂是矿区主要导矿容矿构造。燕山晚期的中酸性岩体及其期后热液富含有用组分为其成矿所需热源。矿床类型以中高温、中温热液交代型为主,外接触高温交代型为辅。
Tongchangpo Cu deposit, Maduan is in the NW part of Laojunshan Sn-Zn muhimetallic metalloge- netic area. The orebody of thia orefieid is in close relation with the magmatlsm, structure, lithologic characters of wall rock of this area. The ore-bearing strata are Cambrian Tianpeng Formation Upper Member marbleized dolomit- ic limestone with intercalation of schist. The main ore transmission and ore-bearing structure is the interlayer slip fault. The heat source of metallogenesis is Late Yanshanian intermidiate-acid rock body and the posterior thermal fluid roch in the useful component. The ore deposit belongs mainly to mid-high, mid T hydrothermal metasomatic type, secondly to outer contact high T metasomatic type.
