江西葛源稀有金属矿床铌钽赋存状态

On the Occurrence States of the Element Nb and Ta in the Superlarge Geyuan Rare Metal Deposit in Jiangxi Province

摘要: 葛源稀有金属矿床中铌、钽矿床赋存于隐伏蚀变花岗岩岩体内，通过对该矿床铌、钽矿化特征及赋存状态的研究，查明矿床中铌、钽两种元素主要以类质同象、独立矿物和包体三种形式存在，独立矿物钽铌铁矿、细晶石是其最主要的赋存形式。

Abstract: The Geyuan Nb-Ta rare metal deposit is hosted in the underground altered granite. The features of Nb and Ta mineralization and Nb and Ta occurrences in this deposit have been studied. Both rare metals in the Geyuan deposit dominantly occur in the forms of isomorphs, independent mineral and inclusion, and the independent minerals are predominately tantaline and microlite.
