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.

在此，斑岩铜矿中伊利石多型可能成为有效的矿化晕指示剂。

The intersecting positions of aeromagnetic lines of different directions and depths were calculated, and characteristics of the integrated anomaly of different elements were described. The fuzzy membership map for the porphyry copper deposit was compiled.

通过模糊推理计算得到该区不同高度、不同方向航磁解译构造的交汇部位以及不同元素的组合异常特征，最终确定了该区可以发现斑岩型铜矿的模糊概率分布图。

It has been successfully applied to the prediction and assessment of Gangdese porphyry copper belt in Tibet.

该项技术已成功地应用于西藏冈底斯斑岩型铜矿的预测与评价中。

This method was originally designed for work with disseminated sulfide bodies , such as porphyry copper deposits.

此法当初是被设计用来勘查浸染状硫化物矿体的。例如斑岩铜矿。

In many porphyry copper deposits, additional enrichment of the metal has been caused by surficial weathering

在许多斑岩铜矿矿床中，地表风化使得金属铜进一步富集。

Lying southeast of Coqen County in western Tibet and tectonically within Lhasa terrain, the Ri'a copper deposit is a skarn copper deposit related to an adamellite porphyry stock.

藏西地区措勤县日阿铜矿产于拉萨地块内，是一个与二长花岗斑岩岩株有关的矽卡岩型铜矿床。

The objective is to subjugate and discourage the people, because that allows the elite to continue to rule unopposed.

其目的是压制和打击人民的积极性，因为这可以让实权派继续统治不会沦为反对派。

GOD,this is the second time you vanquished me!
