| 摘 要： | 康古尔金矿床位于一大型韧性剪切带的次级构造中,容矿围岩为石炭系岛弧火山岩.矿体由蚀变千糜岩和糜棱岩化火山岩的矿化富集地段组成.矿体产状与陡倾的糜棱岩带一致,围岩蚀变有硅化、绿泥石化、绢云母化、黄铁矿化等.从矿体中心到围岩存在明显的构造-蚀变-矿化分带现象.成矿作用具多阶段性,成矿物质主要来自火山岩.韧性剪切带不仅控矿,而且韧性变形变质作用是一种重要的成矿作用.提出了康古尔金矿构造地球化学成矿模式.

| Abstract: | Kanggul gold deposit occurs in a second order shear zone within a large size ductile shear zone on the northern margin of Carboniferous island arc volcanic area Orebodies,hosted by altered phyllonite and mylonitized volcanic rocks,are parallel to the steep dipping mylonite zone The wall rock alterations include silicification,chloritization,sericitization and pyritization Geological studies show that the tectonic altered metallogenic characteristics have zoning phenomenon The doposit is a product of polyphase evolution The ore materials were derived from volcanic rocks The ductile shearing is not only an ore controlling structure,but also a kind of mineralization by its ductile deformation and metamophism A model of metollogenesis of ductile shear zone gold deposit of Kanggul is established |
