摘要: 江西葛源黄山铌(钽)矿床位于灵山花岗岩体西侧的内外接触带上,受赣东北深大断裂及其次级北东向和北西西向断裂的控制。围岩蚀变主要为角岩化、矽卡岩化和黑鳞、铁锂云母岩化等。总体矿化特征,近岩体富铌,远岩体而富钽。

Abstract: Huangshan niobium(tantalum) deposit in Geyuan,Jiangxi province,is located in the internal and external contact zones in the west side of Lingshan granite body,and is controlled by the Northeastern Jiangxi deep-huge fault zone and its subordinary NE and NWW-trending fractures.The major wall-rock alterations are hornfelsization,skarnization,protolithionization and Fe-Li micatization and so on. Overall,the mineralization is characterized by enrichment of niobium in the area close to the granite body and enrichment of tantalum in the area far from the granite body.
