| 摘 要： | 江里沟钨铜多金属矿床位于西秦岭西段,矿床形成时的大地构造背景为三叠纪南部大洋俯冲的岛弧带。矿区由主矿区和周围几个矿点组成,出露的地层主要为下三叠统隆务河群和下二叠统大关山群。多金属矿化主要与矿区南部一个多期侵位的复式花岗岩岩体有关。主矿区以钨、铜矽卡岩矿化为主,分布在岩体北西部附近围岩地层中,同时发现在岩体中有裂隙矿化、石英脉型矿化和浸染状矿化几种型式。主矿区具有典型的成矿分带性特征,表现在成矿元素分带、成矿蚀变分带和成矿构造分带。据此建立了矿床斑岩-矽卡岩-热液脉型综合成矿模式。

| Abstract: | The Jiangligou multi-metal deposit lies in the western part of the West Qinling Mountains,which was an island arc zone formed by the subduction of The South Ocean during Triassic time.The mining area consists of the main mining areas and several small mineralization points.The strata exposed are mainly the Longwuhe Group of Lower Triassic and Daguanshan Group of Lower Permian.Multi-metal mineralization is related to a multi-phase composite granite pluton emplacement,which lies in the south of the mining are... |
