REE Analysis of Thermoluminescent Fluorite
-
摘要: 对中国发现的不同颜色、具热发光性与不具热发光性萤石的稀土元素特征进行了对比研究。结果表明, 具热发光性绿色萤石的Y (33.7×10-6~57.5×10-6) 、Ce (17.1×10-6~53.1×10-6) 、La (11.30×10-6~9.46×10-6) 、Nd (7.17×10-6~8.87×10-6) 、Dy (4.34×10-6~7.00×10-6) 、Gd (2.37×10-6~5.12×10-6) 相对富集, 具热发光性紫色萤石的这6种稀土元素相对亏损, 这也许是其发光性相对较弱的原因, 而不具热发光性萤石的这6种稀土元素的质量分数相当低。Abstract: REE analysis is adopted to study the characteristics of REE of fluorites in different colours. The results show that the green fluorite with thermoluminescence is rich in Y (33.7×10-6~57.5×10-6), Ce (17.1×10-653.1×10-6), La (11.30×10-6~9.46×10-6), Nd (7.17×10-6~8.87×10-6), Dy (4.34×10-6~7.00×10-6), Gd (2.37×10-6~5.12×10-6). The purple fluortie is poor in the six rare earth elements. This is why the luminescence is weak. But the contents of the six kinds of rare earth element are very low in the fluorite without thermoluminescence are very low.
