中文摘要: 永定大坪铌钽矿是中国冶金地质总局第二地质勘查院近年来在矿产调查领域取得的又一项重大找矿成果。矿床赋存于潜火山岩相碱长花岗斑岩内,该类型花岗斑岩是岩浆晚期高度分异和演化的产物。矿床主要有用组分为铌钽矿,伴生铷。资源量估算结果:钽为特大型规模、铌为中型矿床规模、铷为超大型规模。该矿床的发现为福建省内铌钽矿的地质找矿提供了一个新的思路,具有重要的指导意义。

Abstract:Yongding Daping Nb-Ta ore deposit is another important prospecting achievement in the field of mineral investigation in recent years by the Second Geological Prospecting Institute of China Metallurgical Geology Bureau. The deposit was found in the alkaline granitic porphyry of the subvolcanic intrusion facies, which is the product of late magmatic high differentiation and evolution. The main useful constituents of the deposit are Nb-Ta ore and associated Rb. The results of estimating reserves indicates that Ta resource is a special large deposit, Nb resource is a medium-sized deposit, and Rb resource is a super large deposit. The discovery of this deposit provides a new idea for the geological prospecting of Nb-Ta ore in Fujian Province. It has important guiding significance.
