概述金川铜镍矿床位于祁吕贺山字型构造前弧西翼北侧,阿拉善台块内部区与边缘隆起毗连的北西西向F_1大断裂南侧.矿床形成后,被断层错开为四个矿段,自西而东依次为三矿区、一矿区、二矿区和四矿区(图1).含矿超基性岩体侵入于前震旦纪片麻岩和大理岩系中.一、二矿区岩体出露地表,面积1.34平方公里.一矿区矿体埋藏浅,地表有氧化矿露头,是最早被发现和勘探的.三、四矿区岩体小,品位低,均为厚数十米的第四纪砂砾岩覆盖.
Summary The Jinchuan copper-nickel deposit is located on the north side of the northwester west wing of the Qilu-He-Shan mountain structure and is located to the south of the west F_1 fault adjacent to the uplift of the margin in the interior of the Alashan Platform. After the deposit was formed, the fault was dislocated into four ore- From west to east, there are three mines, one mine, two mines and four mines (Fig. 1) .The ore-bearing ultramafic rocks intrude into pre-Sinian gneiss and marble.The first and second ore- Open surface area of 1.34 square kilometers. A ore district buried shallow ore surface oxide ore outcrops, is the earliest discovered and exploration .3, 4 rock mass is small, low grade, are tens of meters thick Quaternary Sandstone cover.
