| 摘 要： | 赛都金矿床位于新疆额尔齐斯构造带北西段,矿体受韧性剪切构造带的控制,赋存于玛尔卡库里巨型剪切带内的蚀变糜棱岩带内.构造-成矿流体早期以中高温、富CO2-N2等挥发分为特征,包裹体均一温度252.0～408.0℃;中期以CO2-H2O流体为主,包裹体均一温度203.0～325.8℃,反映了中温热液特征;中晚期演化为中低温、中低盐度的盐水溶液体系,包裹体均一温度120.0～221.0℃.矿石中黄铁矿的δ34S变化范围在3.53‰～5.88‰之间;铅同位素组成的206Pb/204Pb变化于18.099 7～18.358 5,207Pb/204Pb变化于15.487 7～15.579 0,208Pb/204Pb变化于38.111 6～38.355 1.硫铅同位素研究表明成矿物质是从深部富集的,在造山作用过程中从深部岩石通过热液萃取获得.主要的金矿化与后碰撞造山的伸展构造环境有关,构造-成矿流体的演化特征与剪切带演化过程相吻合.
