舜珑玉及其相似品的红外光谱无损鉴定

Non Destructive Identification of Shunlong Jade and its Analogues by Infrared Spectroscopy

舜珑玉是近年湖南省郴州市临武县境内发现的一种具有玻璃光泽或丝绢光泽的硬水铝石玉石新品种。玉石特征鉴定与研究发现舜珑玉主要含硬水铝石为主,其次含有少量刚玉、石英、方解石、黏土矿物和金属矿物。但从同一矿区采集的样品鉴定和研究发现,很多外观和密度极其相似的样品并非舜珑玉。通过利用傅立叶红外光谱仪对样品进行光谱学特征鉴定,找到了准确、无损、快速鉴别舜珑玉及相似玉石品种的方法。

Shunlong jade is a new variety of hard diaspore jade found in Linwu County,Chenzhou City,Hunan Province in recent years,which has a glass luster or silk luster.The identification and research of jade characteristics found that Shunlong jade mainly contains hard diaspore,followed by a small amount of corundum,quartz,calcite,clay minerals and metal minerals.However,identification and research on samples collected from the same mining area have found that many samples with extremely similar appearance and density are not Shunlong jade.In the research,the Fourier infrared spectrometer was used to identify the spectroscopy characteristics of samples,and an accurate,nondestructive and fast method was found to identify Shunlong jade and similar jade varieties.
