摘要: 北祁连山大坂大岔地区蛇绿岩有关矿产可划分为两个矿化系列:1蛇绿岩同生矿化系列,指蛇绿岩套形成过程随之形成的矿产组合,已知有与变质橄榄岩有关的岩浆成因铬铁矿,基性火山岩有关的海底热液成因块状硫化物铜矿;2蛇绿岩后生矿化系列,指蛇绿岩套形成之后再造形成的矿产组合,已知有破碎带蚀变岩型铜矿和银矿。Abstract: The mineral resources related to ophiolite in Daban-Dacha area of North Qilian Mts.,may be divided into the following two series of mineralization: (1) Syngenetic series of mineralization in the ophiolite,i.e.mineral resources assemblage formed along with forming process of the ophiolite suit,magmatogenic chromite ore related to the metamorphic peridotite and hydrothermal massive sulfide copper ore at seafloor was known to us.(2) Epigenetic series of mineralization in the ophiolite,i.e.mineral resources assemblage recom posed after forming process of the ophiolite suit,altered rock type copperore and silver ore in fracture zone was known to us.
