| 摘 要： | 广西大厂锡多金属矿床的形成与花岗岩关系密切,其中,花岗斑岩呈岩墙状产出,称为"东岩墙",主要分布于西矿带的铜坑—长坡锡矿(大厂锡矿主体矿山)的东侧。通过野外调研和室内岩石学分析表明,"东岩墙"不是单一的花岗斑岩岩墙,而是由近于南北向断裂破碎带的花岗斑岩岩墙、闪长玢岩岩墙和次玄武岩岩墙组成的多期次构造岩浆带。通过岩石化学分析认为,构成该岩墙的岩石属钙碱性-碱性岩浆系列,形成于岛弧及活动大陆边缘环境。"东岩墙"是一条导岩、导矿构造和贯穿大厂矿田的地质界线,其对两侧的矿床分布、矿化强度、矿床类型有明显控制作用。

| Abstract: | The formation of the Dachang Sn-polymetallic deposit is thought to be closely related to granite in the area.One granite porphyries dyke,called the East Dyke,is located in the east side of the Tongkeng Sn and Changpo Sn deposits in the western ore belt.Field research and petrologic analysis shows that the East Dyke is not a simple granite porphyries dyke,but a multistage techtono-magmatic belt composing of nearly NS-trending fracture zone,granite porphyries dyke,diorite porphyrite dyke and basalt dyke.Petro... |
