| 摘 要： | 本文对云南省云龙锡矿六种不同颜色的12个锡石样品进行了阴极射线发光、紫外和可见吸收光谱的研究和电子探针分析,证明不同颜色锡石的发光光谱和吸收光谱没有本质上的差别。锡石颜色的变化一方面与杂质元素Fe、W、Nb、Ti的含量有关,主要的还是锡石本身色带结构所决定;锡石颜色深浅变化还与其形成温度和时间有关。

| Abstract: | Cathode-ray luminescene, ultraviolet-visible radiation absorption spectraland electron microprobe studies have been done on twelve cassiterie samples ofsix different colours from the Yunlong Sn deposit, Yunnan, China. It is foundthat there is no significant difference in luminescence and absorption spectrafor these samples. Although the colour of cassiterite has a bearing on the con-tents of Fe, W, Nb and Ti in it, the main factor is the proportion of brownin cassiterite. The colour variation of cassiterite is dependent on its formationtemperature and time. |
