| 摘 要： | 锡石是南平花岗伟晶岩中分布广泛的重要副矿物,和铌钽矿物密切伴生,且锡石中的钽、铌含量也颇高,Ta2O5最高达4.8%,Nb2O5最高达1.66%,因此,锡石不仅是伟晶岩中铌钽矿体中的标志性矿物,而且完全可综合回收,具有较大的经济价值。对南平伟晶岩中的锡石从产状、分布规律、物理、化学特性及其红外光谱等做了较详细论述,对于探讨铌钽矿化伟晶岩的形成及寻找铌钽矿体有着重要意义。

| Abstract: | Cassiterite is a widespread and significant accessory mineral that it was distributed in the Nanping granitic pegmatites in which cassiterite with Nb-Ta minerals close associate.Nb-Ta content in the cassiterite is highter,Ta_2O_5 up to 4.8%,Nb_2O_5 up to 1.66%.The cassiterite both is typical mineral of Nb-Ta ore bodies in granitic pegmatites and can entirely multipurpose use,have bigger economical value.This article discuss minutely chemical composition.Phsical mature,infrared absorption spectrum,attitude and distribution method of cassiterite in Nanping pegmatites.It have got important significance for research formation of Nb-Ta mineralization pegmatites and look for Nb-Ta ore bodies in pegmatites. |
