铌、钽是具有相同电价和相同离子半径的高产强元素,在各种地质过程中具有非常相似的地球化学特征,具密切的共生关系。铌、钽因具有高强度、抗疲劳、抗变形、抗腐蚀、超导等多种优良特性,成为了电子工业、军事和空间技术及核工业不可或缺的重要材料。铌钽铁矿(Fe,Mn)(Ta,Nb)2O6)是最重要的铌钽矿物之一,其往往赋存于富挥发份的岩浆体系中(Linnen and Cuney,2005)。鉴于熔体中矿物溶解度对矿物晶
Niobium and tantalum are high-yielding strong elements with the same electricity price and the same ion radius. They have very similar geochemical characteristics in various geological processes and have close symbiotic relationships. Niobium and tantalum have become indispensable materials for the electronics industry, military and space technology and the nuclear industry due to their excellent properties such as high strength, fatigue resistance, deformation resistance, corrosion resistance and superconductivity. One of the most important niobium-tantalum minerals is the niobium tantalite (Fe, Mn) (Ta, Nb) 2O6), which is often found in volatile-rich magmatic systems (Linnen and Cuney, 2005). Given the solubility of minerals in the melt on the mineral crystal
