Gemmology of Beryl from Pingwu, Sichuan Province

摘要: 自然界中绿柱石多为柱状晶形,外观呈板状的绿柱石非常少见。四川省平武县板状透绿柱石晶体硕大,晶形完美,透明度高,具有很高的宝石学价值,其奇特的共生组合具有极高的观赏价值。通过化学全分析、红外光谱、X射线粉晶衍射、透射光谱等先进测试技术,对平武板状绿柱石的地质产状、形态特征、物理性质等进行了初步研究,探讨了其发展前景。

Abstract: Beryl from Pinwu, Sichuan Province, has the colour from light green to colourless, with the transparence from transparent to semi transparent and the shape of plate. Because of its special and beautiful co-existent compositions the beryl is prized as a gem for people to appreciate when it is clear and free from flaws. This unique characteristic has drawn wide attention among the mineralogists. Its physical property, mineral genesis and the cause of colour shades are surveyed by way of X-ray powder diffraction, analysis of chemical compositions, infrared spectrum and other techniques. Some precious new information of the beryl is obtained. The beryl is expected to have a promising future in application because it has a comparatively high value.
