摘　　要：肃北黑山铜镍矿区构造位置属于塔里木板块东北边缘,处于多期板块拼裂而形成的复杂造山带上。为揭示该地区铜镍等多金属成矿规律和控矿因素,本文从区域地质背景、矿区地质特征以及矿床地质特征等几个方面探讨了肃北黑山铜镍矿的成矿条件,通过分析认为,该矿床为岩浆热液型熔离矿床,铜镍等主要成矿物质来源于上地幔,金属硫化物和金属氧化物的晶出发生在岩浆后期含矿热液作用下。Heishan copper-nickel deposit bed is located in the northeastern edge of the Tarim plate,and geologically situated at a complicated orogenic pattern with multi-island ocean features.To reveal the metallogenic regularity and metallogenic controlling factors of the polymetallic ore such as copper-nickel deposit,This article gave detailed presentation about the cause of ore s forming from aspects of the regional geological environment,an overview about ore-field geology,Geological characteristics of ore-belt a...
