X射线荧光光谱技术与拉曼光谱技术在齐家文化玉器研究中的应用

Application of XRF and Raman spectrometry in the study of Qijia culture jade

为分析判断齐家文化玉器的材质,利用X射线荧光光谱技术对宁夏博物馆藏5件齐家文化玉器进行无损检测分析。结果表明,5件玉器所含元素及相对含量与和田玉相似。再借助齐家文化历史史料的有关信息,可推断为和田玉成分;利用拉曼光谱技术测得5件样品的拉曼光谱图,通过与和田玉样品拉曼光谱图比对,最强及次强特征峰位整体与之相似。可以明显看到透闪石矿物的特征峰,两种检测分析结果相互验证。研究结果为探索齐家文化玉器的玉质和玉料来源提供了重要的科学依据和准确的数据支撑。

In this study,X-ray fluorescence (XRF) spectrometry,a nondestructive analytical method,was used to test and analyze the components and structures of five Qijia culture jade samples from Ningxia Museum.The analytical results show that the elements and their respective contents of the five samples are similar to those of Hetian jade.Furthermore,based on historical information about the Qijia culture,it can be inferred that the samples are made of Hetian Jade.We also made a comparative study using laser Raman spectrograms of the five samples and a Hetian jade sample.The result shows that their highest and second highest characteristic peaks are mostly similar.The peak of tremolite is quite clear in the spectrogram,which confirms the XRF result.The study provides a vital scientific basis and accurate data support for further research on materials and on the origin of Qijia jade.
