Geochronology and petrogenesis of biotite granite from the Gaocheng Pb-Zn-Ag deposit, in western Guangdong Province, China

  • 粤西高枨大型铅锌银矿赋存在黑云母花岗岩中,本文采用LA-ICP-MS锆石U-Pb测年获得黑云母花岗岩的结晶年龄为429±13Ma,为早志留世,属于加里东期岩浆活动的产物。详细的地球化学分析显示岩石的SiO2含量为(64.33%~74.54%,平均为68.67%),Al2O3含量偏高(13.88%~16.61%),碱质含量高(K2O+Na2O=5.31%~7.89%),低P2O5( < 0.25%) 含量,强过铝质(A/CNK=1.07~1.32)。岩石富集LREE和Rb、K、U、Pb,贫Ba、Sr、Nb、P、Ti元素,铕呈负异常(Eu/Eu*=0.38~0.90)。以上特征表明该岩体属于钙碱性强过铝质花岗岩。经年龄校正后的206Pb/204Pb,207Pb/204Pb和208Pb/204Pb值分别为17.458~18.131、15.563~15.638和37.547~38.406。Sr初始值变化范围较大((87Sr/86Sr)i=0.7091~0.7259),但εNd(429Ma) 值相对较低(-8.9~-6.1),暗示岩体来源于元古代(t2DM=1.67~1.83Ga) 的地壳组分,其源岩主要为含少量泥质的砂岩质组成。结合区域地质背景的综合分析,认为高枨黑云母花岗岩与华夏板块与扬子板块发生板内碰撞-拼合事件有关,由元古代地壳物质重熔形成的形成的S型花岗岩。
