摘要
南岳岩体位于江南造山带北东部位,其附近发育大规模稀有金属矿化,前人鲜有报道与南岳岩体稀有金属成矿的相关消息。文章通过对南岳岩体的岩相学与地质地球化学特征进行分析,认为南岳岩体第一期花岗岩与第四期花岗岩为同源关系,但第四期花岗岩分异演化更为完善,且与Sn-W-U稀有金属矿化联系密切,为稀有金属找矿远景区。稀有金属成矿可能与花岗岩岩石演化程度存在正相关关系。
Nanyue pluton is located in the northeast of Jiangnan orogenic belt,this area has large-scale rare metal mineralization.However,there is little literature referring to the mineralization of rare metals in Nanyue pluton.Based on the analysis of the petrographic and geogeochemical characteristics of the Nanyue pluton,this paper concludes that the granite of the first stage and the fourth stage of the Nanyue pluton have same source,but the fourth stage has a higher level of differentiation and evolution,and is closely related to the mineralization of Sn-W-U rare metals,thus providing a prospecting prospect for rare metals.The mineralization of rare metals is positively correlated with the evolution of granite rocks.
