摘要
玉西银矿床为东天山地区唯一一处独立银矿床,位于中天山老地块,阿拉塔格-尖山子大断裂北侧,区内地质构造复杂,岩浆岩发育,非常有利于银矿富集.通过对区内地质特征、矿床特征和控矿因素、矿物共生组合特征等综合分析,初步建立了"玉西银矿床"找矿模式,并确定其成因类型是在构造和构造动力控制下的中低温破碎蚀变岩型银(铅、锌)矿床,该银矿床的发现打破了在中天山老地块中一直未能找到独立型银矿床的局面,也对在该区寻找该类型的矿床提供了依据与找矿标志.
The Yuxi silver deposit in Hami,Xinjiang is the only independent type in east Tianshan area, which is located in the old land of middle Tianshan and the north of ALATAGE-JIANSHANZI fault. The geological structure is complicated and the magma rock develops in that area, which are very beneficial to the silver mineral. We will initially built the model of looking for Yuxi silver mineral through comprehensive analysis in geology characteristic, deposit characteristic, ore factor, mineral colacobisis characteristic and so on.. And then we will ascertain the genetic type is the broken alteration of middle low temperature rock type silver （lead, zinc） deposit between the controlling down in structure and structure driving force. Its finding and exploration have broken the circumstance of not finding the independent type deposit in the old land of middle Tianshan, and provided a basis and a standard for seeking that type in that area, which is very significant.
