Abstract:

新疆望峰金矿区金的成矿作用与硅化作用密切相关,文章通过对矿区典型矿体的赋矿围岩、蚀变岩石及矿石进行Si同位素组成研究,探讨了成矿流体中硅质来源、演化过程及其成矿意义。结果表明:①望峰金矿体围岩具有较均一的Si同位素组成,δ30Si=-0.2‰(n=3),显示了花岗质原岩Si同位素组成特征,动力变质作用对原岩硅同位素组成无明显影响;②蚀变岩石Si同位素组成均一性较高,δ30Si=-0.1‰(n=3),显示了花岗质原岩Si与成矿期热液Si的混合特征;③矿石Si同位素组成变化范围较大,不同类型矿石的Si同位素组成差异较明显:硅化蚀变糜棱岩型δ30Si=-0.5‰~-0.2‰(n=9),集中于-0.3‰~-0.2‰,平均-0.3‰;硅化蚀变岩型δ30Si=-0.3‰~-0.1‰(n=9),平均-0.2‰;热液石英脉型δ30Si=-0.3‰~0.1‰(n=6),平均-0.1‰。望峰金矿区金成矿流体中的硅质,主要来源于花岗质赋矿围岩。矿石中Si同位素组成变化较大,是富硅成矿流体演化过程中发生Si同位素动力学分馏的结果,矿体下部及矿区深部应有一定的找矿前景。
