| 摘 要： | 分析了云开地区粤西庞西垌－桂东南金银金成矿事晚燕山花岗岩的特征与成矿作用的关系。认为晚燕山期英桥花岗岩体属于过饱和富钾质的钙碱性花岗岩系列，是同熔型花岗石。晚燕山期岩浆活动与银金矿床在空间和时间上密切相关，在微量元素、稀土元素、稳定同位素和包体成分等地球化学特征上具有相似性，晚燕山期岩浆活动对银金矿床的形成起着重要的作用。

The Relationship between Late Yanshanian Magmatism and Association of Ore-forming Elements in Pangxidong-Jinshan Silver-Gold Metallogenic Belt,West Guangdong |

| Abstract: | The Pangxidong-Jinshan silver_gold metallogenic belt,located in the border area between Guangdong and Guangxi,include a series of deposits distributed along the Pangxidong-Jinshan fault, The Late Yanshanisn granites in the belt are of Type I. The silver-gold deposits and the granites are closely related to each other, and characterized by very similar trace elements, REE and Pb isotopes and fluid composition. The Late Yanshanian magmatism may have provided part of hydrothermal solution and metallogenic materials for mineralization. |

| Keywords: | granites mineralization silver-gold deposit South China |
