新疆萨尔朔克多金属矿床地质特征及矿床成因分析

Geological characteristics and genesis of salshuke polymetallic deposit,Xinjiang

萨尔朔克矿区处于玛尔卡库里反“S”型构造带中的南北向构造向北西向构造转折端附近,构造作用强烈,成矿作用与火山活动和火山机构密切相关。矿区各矿体主要产于萨尔朔克古火山机构火山通道相的流纹斑岩体中及其接触带部位,主要为铜、金、铅锌多金属矿体。该矿为阿舍勒晚古生代拉张火山盆地中受火山通道相控制的次火山热液型多金属矿床,矿体产于火山通道相的流纹斑岩体中,总体属VMS成矿系统范畴。

The salshuk mining area is located near the North-South structural turning point of the anti-s-type structure belt in the markakuri,with strong tectonic action.The mineralization is closely related to volcanic activity and volcanic mechanism.The ore bodies in the mining area mainly occur in the rhyolitic porphyry of the volcanic channel facies of the salshuk ancient volcanic mechanism and its contact zone,mainly copper,gold,lead-zinc polymetallic ore bodies.The deposit is a subvolcanic hydrothermal polymetallic deposit controlled by volcanic channel facies in the late Paleozoic extensional volcanic basin of Ashele.The ore body occurs in rhyolitic porphyry of volcanic channel facies and belongs to VMS metallogenic system in general.
