| 中文摘要: |
| 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60%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(FeO)/w(FeO+MgO)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。 |
| 英文摘要: |
| 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. |
