| 摘 要： | 桂东大瑶山金矿成矿区是广西主要金矿成矿区之一,龙水、桃花、古袍等金矿是其典型代表。本文着重对该区与金矿相关的花岗岩类特征研究,分析了花岗岩岩石学、岩石化学、微量元素、稀土元素特征,认为:该区不同类型花岗岩大多属于同熔型花岗岩系列,其中以中酸性的花岗闪长岩类岩体与金矿有成生联系。

| Abstract: | Mt. Dayaoshan metallogenetic province in East Guangxi is one of major gold metallogenetic provinces in Guangxi. The typical examples there are Longshui. Taohua. Gupao, etc. . gold deposits. The paper emphatically studies the granitoid related to gold deposits, especially the petrology. petrochemistry, trace elements and REE of granite. Finally, the paper considers that most of granitoid belong to syntectic granite series, among which, the intermediate-acid granodiorite is associated in genesis with the gold deposits. |
