新疆伊宁县金山金矿床是一正在进行勘探的大型金矿,属于浅成低温热液型金矿,金山金矿床产于早石炭纪大哈拉军山组火山岩下部,容矿岩层受热液蚀变和构造角砾岩化作用形成了热液角砾岩。矿体呈似层状,与围岩呈渐变关系。矿石具角砾状、浸染状和网脉状构造。矿石矿物主要以黄铁矿为主,其次为自然金、含银自然金;脉石矿物以石英为主,其次为重晶石、迪开石、高岭石、绢云母等。矿区围岩蚀变作用主要有硅化、黄铁矿化、高岭土化、绿泥石化和碳酸盐化。矿体受断裂构造、不整合面和热液角砾岩等控制,其中北西向和南北向断裂是成矿控制断裂。成矿控制条件具有“三位一体”的特点。
The Jinshan gold deposit in Yining County, Xinjiang is a large-scale gold deposit currently under exploration and belongs to epithermal-type gold deposits. The Jinshan gold deposit is produced in the lower part of the Dajarajianshan Formation volcanic rocks in the Early Carboniferous. Variation and tectono-brecciation formed hydrothermal breccia. Ore body is like layer, and the rock has a gradual relationship. Ore with brecciated, disseminated and reticulate structure. The ore minerals are mainly pyrite, followed by natural gold and silver-containing natural gold. The gangue minerals are mainly quartz, followed by barite, dickite, kaolinite and sericite. Surrounding rock alteration in the mining area mainly includes silicification, pyrite, kaolinization, chloritization and carbonation. The ore body is controlled by the fault structure, unconformity surface and hydrothermal breccia, among which the NW and NS faults are metallogenetic control faults. The conditions of metallogenic control have the characteristics of “Trinity ”.
