云南省马厂箐斑岩型铜钼金矿床岩浆作用及矿床成因的中期报告摘要：云南省马厂箐斑岩型铜钼金矿床位于大理地块的东界，是大理地块北缘一系列蛇绿岩带间断延伸的一大型铜钼金多金属矿床。该矿床以高品位铜、钼、金、银和锡等为主要矿物，矿床规模庞大，潜力巨大，开发价值极高。本文从岩浆作用及其对矿床成因的影响入手，对马厂箐铜钼金矿床的成矿过程进行了初步研究，为后续工作提供了理论依据。关键词：马厂箐斑岩型铜钼金矿床；岩浆作用；矿床成因；成矿过程。Abstract：TheMaChangJingporphyrycopper-molybdenum-golddepositislocatedontheeasternedgeoftheDaliblock,andisalarge-scalecopper-molybdenum-goldpolymetallicdepositthatintermittentlyextendsbetweenaseriesofophiolitebeltsonthenorthernmarginoftheDaliblock.Thedepositismainlycomposedofhigh-gradecopper,molybdenum,gold,silverandtin,andhasalargescaleandgreatpotentialfordevelopmentandhighvalue.Thispaperstartswiththemagmaticactivityanditsinfluenceonthegenesisofthedeposit,andpreliminarilystudiestheore-formingprocessoftheMaChangJingcopper-molybdenum-golddeposit,whichprovidestheoreticalbasisforsubsequentwork.Keywords:MaChangJingporphyrycopper-molybdenum-golddeposits;magmaticactivity;genesisofdeposit;ore-formingprocess.
