摘要
针对市场上出现的三种仿和田玉品种叶腊石岩、蛇纹石滑石岩、透闪石质玉(含碳酸盐),采用常规宝石学鉴定仪器以及偏反光显微镜、红外光谱仪对样品的折射率、相对密度、矿物组成及红外光谱特征进行分析检测,通过对比研究认为三种仿和田玉品种虽在外观上与和田玉极为相似、难以区分,但其常规宝石学参数、主要组成矿物、红外光谱谱峰等特征均与和田玉有所不同,在实验室测试条件下可将其准确区分。
Three kinds of imitation Hetianyu jade which are rare found in the market were collected and analyzed.The samples were analyzed and detected by conventional gemological identification instruments,partial reflection microscope and infrared spectrometer.The three imitation Hetianyu jade varieties are pyrophyllite,serpentinization talcum and tremolite jade(including carbonate).Although the three imitation Hetian Yu varieties are very similar to hetian Yu in appearance,they are different in conventional gemological parameters,main constituent minerals,infrared spectrum peaks and other characteristics,so they can be accurately distinguished under laboratory conditions.
