摘要
文章通过红外光谱、拉曼光谱、紫外-可见光光谱、电感耦合等离子体质谱(ICP-MS)等测试技术和薄片鉴定方法对“独龙玉”的矿物组成、显微结构、颜色成因进行了研究分析。结果表明“独龙玉”主要矿物为石英,次要矿物为鳞片状、少数呈片状铬云母及黄铁矿等,局部偶见土状褐黄色高岭石矿物沿石英颗粒间隙呈细脉状充填。“独龙玉”的过渡金属元素中Cr、Ni、V含量较高,其绿色主要为Cr3+晶体场中八面体配位的两组电子跃迁所致。该研究为“独龙玉”的颜色成因造成的市场困扰提供了鉴别参考,为该玉石的科学鉴定提供了数据支持。
In this paper,the mineral composition and color-genesis of"Dulong Jade"were examined and analyzed through testing techniques such as infrared absorption spectra,Raman spectra,UV-Vis spectra,ICP-MS and thin section identification.The results indicate that the main mineral of"Dulong jade"is quartz,the secondary minerals are flaky fuchsite,a few schistose fuchsite and pyrite;locally,earthy brown-yellow kaolinite minerals are filled as veinlets along the gaps between quartz particles occasionally.In"Dulong Jade",the transition metals of Cr,Ni,and V are relatively high.The result indicates that the green color of"Dulong Jade"is caused by two sets of electron transition in the octahedral coordination of Cr 3+crystal field.This study clarifies the causes of"Dulong Jade"is color distribution,providing references for its the market identification,and provides scientific data for its scientific identification.
