新疆塔吾尔别克金矿矿床地质特征及成矿规律探讨
|
摘要
新疆塔吾尔别克金矿位于著名的阿希金矿附近,矿床产于下石炭统大哈拉军山组第5段安山岩及安山质凝灰岩中,矿床主要受NW—NNW向构造蚀变带的控制,同时次火山相二长斑岩、爆破角砾岩筒(隐爆角砾岩)对成矿也具控制作用;蚀变类型主要有黄铁绢英岩化、硅化、碳酸盐化,热液成矿期包括石英-黄铁矿、石英-硫化物和石英-碳酸盐等3个阶段,形成蚀变岩型、石英脉型和石英-碳酸盐脉型3种金矿化类型,表生期形成氧化金矿。在阐述矿床地质特征基础上,归纳出构造控矿规律、火山-次火山岩体控矿规律、中-低温成矿规律和多因复合成矿规律,综合勘查和研究成果,认为矿床的成因类型为与晚古生代早-中期火山热液有关、有次火山(斑岩型、爆破角砾岩筒型和隐爆角砾岩型)热液成矿作用叠加的浅成低温热液型金矿床。
Tarwuerbieke gold deposit is near to the well known Axi gold deposit occurring in andesite and andesitic tuff of the 5 th Member of Lower Carboniferous Dahalajunshan Formation.It is mainly controlled by NW—NNW cataclastic alteration zone and subvolcanic monzonic porphyry and crypto-blast breccia pipe.Cataclastic alteration rock type gold ore is associated with beresitization,sicification and carbonatization.The ore-forming process is divided into quartz-pyrite,quartz-sulfide,quartz-sulfate stages during which the cataclastic alteration rock type and quartz vein type and sulfate vein type of Au ore were formed and oxide ore formed by supergene process.Based on the geological characteristics and induced ore-control law of fault,volcanic-sub-volcanic rocks and meso-epithermal metallogeny and multi-control factors and synthetic prospecting results the gold deposit is considered a Late-Middle Paleozoic volcanism-related epithermal gold deposit overprinted by sub-volcanic hydrothermal fluid.
