摘要
辽宁岫岩是中国新石器时期红山文化玉器的重要来源,辽宁岫岩的闪石玉可分为河磨玉(籽料)和老玉(山流水和山料)两种。文章利用拉曼光谱技术对两种玉料中发现的石墨包体进行了测试分析。结果显示,两种玉料中石墨包体拉曼光谱的特征明显不同,反映了两类闪石玉形成条件上存在的差异,它们是不同成矿期次或者是不同成矿部位的产物。显然,拉曼光谱技术可以成为无损鉴定玉料产地来源的重要辅助手段。
Xiuyan,Liaoning was an important locality of jade material of the Red Mountain Culture in the Neolithic Age in Chinese history where there are two types of raw material of nephrite jades,namely gravel nephrite jade（Hemo Yu in Chinese） and old nephrite jade（Lao Yu in Chinese）.In the present paper,Laser Raman spectrum technique was applied to analyze the graphite enclaves in the nephrite jades of the two types of materials.The results show that the graphite enclaves in the two types of jades have different characteristics of Raman spectra,indicating that they probably were formed under different geological conditions,or originated from different ore-forming periods or were exploited from different section of ore body.Hence,laser Raman spectrum technique could be used as a supplementary measure for nondestructive detection to determine the occurrence of jades.
