Petrological,geochemical and Nd,Sr,Pb isotopic studies indicate that the ore-hosting volcanic rocks of Xiongcun supperlarge copper-gold deposit in the Gangdese copper belt, Tibet belong to dacite porphyry with ultro-shallow emplacement.

岩石学、地球化学和Nd、Sr、Pb同位素研究表明，西藏冈底斯铜矿带雄村特大型铜金矿床的容矿火山岩为一套具超浅成侵入特点的英安斑岩，SiO2含量集中在61.97%～64.31%之间，富Na2O、低K2O， Na2O/K2O比值平均为5.25。

The authors dated the zircons from the mineralized porphyritic granite and quartz_monzonite porphyry in this deposit by using the LA-ICP-MS U-Pb dating method. The results show that the two ore_bearing intrusions were emplaced in Middle Devonian and Early Permian, respectively.

文章以近年发现的玉勒肯哈腊苏铜矿床为主要研究对象，对矿区内铜矿化的斑状花岗岩和石英二长斑岩进行了锆石U_Pb法精确定年。

The classic PCDs model, proposed by Lowell and Guilbert （1970）, has been widely accepted by economic geologists because of its practical value in the exploration of PCDs in the arc setting, especially in the Circum-Pacific Belt.

然而，近年来国内矿床学家发现，除经典成矿模型所记录的岛弧及陆缘弧环境外，斑岩铜矿还可产于碰撞造山带内，甚至产在陆内环境中。

Therefore, the illite polytype might be an effective indictor for mineralization of porphyry copper deposit.
