北祁连造山带西段红川铜镍矿Ⅲ号超基性岩特征研究

A study on the characteristics of the No.III ultra-basic rock in Hongchuan copper-nickel deposit,western North Qilian Orogenic Belt

2022年,甘肃省地质矿产勘查开发局第四地质矿产勘查院在北祁连造山带西段首次发现了一处中型岩浆熔离型镍矿床—红川铜镍矿,该矿床自发现以来主要开展了矿产勘查工作,各类研究性工作比较薄弱,对含矿超基性岩体研究鲜有报道,笔者等首次对红川铜镍矿Ⅲ号岩体系统补充分析了其岩相学和地球化学特征,同时对该含矿岩体形成的深部构造背景和含矿性进行探讨。

In 2022,the Fourth Geological and Mineral Exploration Institute of the Gansu Provincial Geological and Mineral Exploration and Development Bureau discovered for the first time a medium-sized magma melting type nickel deposit———Hongchuan copper—nickel deposit in the western section of the North Qilian Orogenic Belt.Since its discovery,the deposit has mainly carried out mineral exploration work,and various research works are relatively weak.There are few reports on the research of ore bearing ultrabasic rocks,for the first time,authors conducted a supplementary analysis of the petrographic and geochemical characteristics of the No.III ultrabasic rock system in the Hongchuan copper nickel depsoit,and explored the deep structural background and ore bearing potential of the ore bearing ultrabasic rock.
