摘要
金子仑斑岩钨矿床产于泥盆系中统棋梓桥组灰岩与跳马涧组砂页岩接触面及其附近,受北北东向断层控制.岩体垂直分带明显.钨矿化与萤石化、硅化关系密切.矿床规模大,品位高,是印支-燕山期多期次成矿作用的产物.
The Jinzilun Porphyry tunsten deposit is located at the contact area between the limestone of themiddle Devonian Qiziqiao Formation and the sandy-shale of the Tiaomajian Formation, and its surrounding areas. The deposit is controlled by a NNE striking fault and the intrusive has a distinct verticalzoning. Mineralizations are directly proportional to the intensity of flouritization and silicification. Thedeposit, large in size and high in ore grade, is considered to be a multiple minerogenesis product duringthe Indo-Chinese to Yanshanian epoch.
