新疆萨热克砂砾岩型铜矿人工重砂特征及找矿意义

Characteristics of artificial heavy concentrate and its ore prospecting significance in Sareke glutenite type copper deposit,Xinjiang

萨热克铜矿床位于新疆乌恰县萨热克巴依陆内拉分盆地中,区内地质构造活动强烈,近年来陆续发现了一系列铜铅锌等多金属矿床及大量矿化点,本次研究在收集前人地质资料前提下,通过对研究区重砂矿物成分以及矿物的组成和含量分析研究,表明重矿物以黝铜矿、褐铁矿为主,蚀变矿物以石英、长石、孔雀石为主;辉绿岩脉对于铜的富集具有促进作用,辉绿岩脉群和盆地流体具有叠加成岩成矿特征。

The Sareke copper deposit is located in the Sellakebayi inland pull-out basin in Wuqia County,Xinjiang.The geological tectonic activity in the area is strong.In recent years,a series of polymetallic deposits such as copper,lead,zinc,and a large number of mineralization points have been discovered.On the premise of collecting previous geological data,this study used field geological survey sampling and analysis,and analyzed the heavy sand mineral composition and the composition and content of minerals in the study area.The research shows that the heavy minerals are mainly ore copper and limonite.Light minerals are mainly altered minerals such as quartz and carbonate;diabase veins promote the enrichment of copper,and diabase vein groups and basin fluids have superimposed diagenesis and mineralization.
