铌钽矿物是福建南平花岗伟晶岩中最有工业利用价值的矿物,其种类较多,根据晶体结构和成分的差异,可分成6大类。即:铌铁矿钽铁矿类;重钽铁矿类;锡锰钽矿类;细晶石类;褐钇铌矿类;铌(钽)铁金红石类。铌铁矿钽铁矿还可进一步分成6个亚类。不同种类铌钽矿物产于不同类型伟晶岩或同一类型伟晶岩的不同矿物组合带。在详细讨论了各类铌钽矿物的产状、成分、物理性质及晶体结构等特征的基础上,探讨了它们的地球化学演化规律。 Niobium and tantalum minerals are the most industrially valuable minerals in the Nanping granitoids in Nanping. There are more types of niobium and tantalum minerals, which can be divided into six categories according to the differences in crystal structure and composition. Namely: niobium iron ore tantalite; heavy tantalum ore; tin manganese tantalum ore; fine spar type; brown yttrium niobium ore; niobium (tantalum) iron rutile. Niobium ore tantalite can be further divided into six sub-categories. Different types of niobium-tantalum minerals are produced on different mineral assemblages of different types of pegmatites or of the same type of pegmatite. Based on the detailed discussion on the characteristics of various niobium and tantalum minerals, such as their origin, composition, physical properties and crystal structure, their geochemical evolution rules are discussed.
