摘要
电气石是一种含挥发分的硅酸盐矿物 ,作为副矿物的电气石与其他矿物共生 ,且含量较少 ,但在电气石岩中可达 6 0 %以上 ,以前很少被人们重视。近 10年来 ,随着对一些大型锡、钨等矿床的勘探和研究 ,发现电气石与这些矿床有着密切的关系。分析对比电气石成分中 w(Fe O) / w(Fe O+Mg O)的比值 ,把国内几个有关矿床与国外一些典型矿床作比较 ;再借鉴前人对典型矿床中的电气石进行硼同位素的研究结果 ,找出不同特征电气石与不同矿床之间的关系。
Tourmaline is a silicate mineral containing volatile component occuring together with other minerals as accessory mineral in minor content, but its content is over 60% in the tourmaline rock and is rarely studied before. Studies and exploration of large size Sn and W ore deposits in recent 10 years show close relation of tourmaline with them. Comparison of FeO/(FeO+MgO) of tourmaline in some of the deposits in China and those abroad, together with boron isotope results for some typical deposits reveal that certain tourmaline characteres correspond to certain ore deposits.
