宝石学基本测试法在辽宁宽甸蛇纹石玉特征中的应用研究

Study on the application of basic gemology test method to the characteristics of serpentine jade in Kuandian,Liaoning province

辽宁省丹东市宽甸满族自治县2013年9月发现了一块巨型玉石,该巨型玉石位于滑石矿坑内,赋存于大石桥组地层的蛇纹石化大理岩中。该巨型玉石被发现后在全国引起轰动,受到各界重视,但对其一直缺乏科学系统的研究。文章采用宝石学基本测试方法配合偏光显微镜、红外光谱仪等,对辽宁宽甸蛇纹石玉的矿物组成进行了初步研究。宽甸蛇纹石玉的主要矿物组成为叶蛇纹石,块状构造,显微变晶结构,文章也对宽甸蛇纹石玉市场前景进行预测。

In September 2013, a giant jade is found in Kuandian Manchu Autonomous county, Dandong city, Liaoning province. The giant jade is located in a talc mine and is located in the serpentine petrochemical marble in the strata of Dashiqiao formation. The giant iade has caused a national sensation since it was discovered, but it has been lack of scientific research. In this paper, the mineral composition of serpentine jade from Kuandian, Liaoning province is studied by using gemmology and polarizing microscope and infrared spectrometer. The main mineral composition of Kuandian serpentine jade is serpentine, block structure and microcrystalline structure. At the same time, the market prospect of Kuandian serpentine jade is also predicted.
