阔尔真阔腊金矿床地质地球化学特征

阔尔真阔腊金矿是８０年代后期新疆萨吾尔山发现的金矿床。该矿床形成于海西晚期岛弧环境，矿化赋存在次火山岩及隐爆角砾岩中，矿化富集受断裂控制。岩石化学、包裹体地球化学和稳定同位素地球化学特征研究表明，成矿物质主要来自地壳深部，成矿流体人混合来源，成矿与海西晚期中－基性火山岩浆分异演化有关。

GEOLOGICAL AND GEOCHEMICAL FEATURES OF THE GOLD DEPOSIT OF KUOER ZHENGKUONA,XINGJIANG

The gold deposit of Kuoer Zhengkuona was discovered in late eighties in Sauer Mountains of Xinjiang,formed in island arc environment during Hercynian period.The mineralization occurred in sub volcanic rocks and cryptoexplosion breccia, the enrichment of mineralization being controled along faults.The studies of petrochemistry,geochemistry of fluid inclusions and stable isotopes show that the ore forming matter came from the deep crust,and the ore forming fluid was of mixture origin, and the metallogeny was related with the differentiation and evolution of the middle basic volcanic magma in late Hercynian period.
