Keyword:  黄色蛇纹石玉光谱特性热处理仿古;
Abstract: 通过运用x射线荧光光谱、紫外一可见吸收光谱、差热分析、红外光谱和拉曼光谱测试对少见的黄色蛇纹石玉进行成分和结构的分析,结果表明其主要成分为利蛇纹石.利蛇纹石的红外光谱具有由Si-O伸缩振动引起的956cm-1,1080cm-1,3650cm-1肩吸收的特征吸收峰.少见的黄色经紫外-可见吸收光谱测定得出363nm,384nm吸收峰,主要是由杂质离子Fe3+离子的d-d晶场跃迁引起.经过高温加热处理后,蛇纹石玉失去结构水转变为新的物相镁橄榄石,拉曼峰825m-1和856em-1是镁橄榄石的特征谱峰.由热处理法制得的仿古效果,对于仿古玉的鉴定具有一定的研究意义和价值.
