Wollastonite in Qinghai Nephrite Jade and Its Significance

摘要: 经镜下观察和X射线粉晶衍射分析发现,青海软玉中普遍含有硅灰石,这与新疆软玉形成了鲜明的对比。硅灰石的存在增加了青海软玉的透明度,降低了油润度,对青海软玉的质量产生较大的影响。

Abstract: Based on the optical observation and X-ray powder diffraction, the compositions of Qinghai nephrite jade are studied. The results show that Qinghai nephrite jade contains wollastonite commonly, which is different from Xinjiang nephrite jade. Wollastonite enhances the transparency of Qinghai nephrite jade and reduces its luster. The wollastonite may be one of the main reasons that influence the quality of Qinghai nephrite jade.
