摘要
哈萨克斯坦北天山金矿床成矿作用时间为二叠纪末至三叠纪,是天山晚期后碰撞阶段的产物,具典型的低硫型浅成低温热液金矿床特征。区内矿床受构造-火山岩共同控制,矿床以火山穹隆为中心沿NE向破碎带形成规模较大的矿体,沿NW向和近EW向形成小矿体,在交叉部位形成厚大的富矿体。在垂向上地表以金银矿化为主,向深部过渡为铜铅锌矿化,底部演变为含铜矿化侵入岩脉。
Metallogenic age of Kazakhstan North Tianshan gold deposit is from lower Permian to Triassic,it is results of the late Tianshan collision stage,with typical character of low sulfur type epithermal gold deposits. The deposit is con-trolled by tectonic - volcano rock, The volcano dome as the center of desposit with Northeast fracture zone formed large ore bodies,norhwest and sublatitudinal formed small orebody in trend,and formed thick rich orebody in cross section; In the vertical direction, shallow to gold-silver mineralization, into the deep transition for the copper -lead- zinc mineraliza-tion, the bottom for the evolution of intrusive rock stock with containing copper mineralization.
