分析了云开地区粤西庞西垌－桂东南金山银金成矿带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铝过饱和富钾质的钙碱性花岗岩系列，是同熔型花岗岩。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 the characteristics of the Late Yanshan granite and the metallogenic activities in the Jinshan silver gold metallogenic belt in the west of Guangdong province in the Pangxiu section of western Guangdong Province in the Yunkai area was analyzed. It is considered that the Late Yanshanian Yingqiao granite body belongs to the series of Al-supersaturated and potassium-rich calc-alkaline granite, which is the same type of melted granite. The Late Yanshanian magmatic activity is closely related to the silver-gold deposit in space and time, and has similar geochemical characteristics such as trace elements, rare earth elements, stable isotopes and inclusions. The Late Yanshanian magmatic activity was responsible for the formation of silver-gold deposits It plays an important role.
