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。
The ore-related minerals of the ophiolite in the Daban area of the Dabashan Mountains in the northern Qilian Mountains can be divided into two mineralization series: 1 The symbiotic mineralization series of ophiolite refers to the mineral assemblage formed after the formation of the ophiolite casing. There are known mineral assemblages associated with metamorphic olives Rock-related chromite, basic volcanic rocks associated with the seafloor hydrothermal massive sulphide copper ore; 2 ophiolite epigenetic mineralization series, refers to the formation of ophiolite formation after the formation of the mineral combination is known to have Broken zone altered rock copper and silver ore.
