| 摘 要： | 越城岭-猫儿山地区花岗岩类岩石出露很广，侵入时代从加里东期至燕山期，为一套富硅、铝过饱和、燕山早期花岗岩体略富碱、分异演化程度较高的中粒-细粒黑云母花岗岩、二云母花岗岩和白云母花岗岩。岩石具有明显的富K2O，贫Na2O特征，为富含W、Sn、Pb和Bi的岩体，具备了为钨锡多金属矿化提供成矿物质和成矿热流体的内在条件。区内钨锡钼矿化与燕山早期花岗关系密切，矿床（点）产于细粒花岗岩周边、细粒花岗岩体与围岩接触带附近。

| Abstract: | The Granites are extensively exposed in the Yuechengling-Miaoershan region,ranging in age from Caledonian to Yanshannian.This suit is comprised of middle-fine-grained biotite-granites,fine-grained muscovite-biotite-granites and fine-grained muscovite-granites which are rich in silica,alkalis,aluminum,high evolution and high differentiation.The granites are K2O rich and Na2O poor and W-Sn-Pb-Bi-rich rocks.W-Sn-Mo metallogenesis is correlated to early Yanshannian granites in the area.The majority of deposits ... |
