摘　　要：近期,一种新型“草莓晶”石英岩玉充填处理品出现在市场上,充填物与红色矿物包裹体相似,基础宝玉石学折射仪检测其折射率为1.54(点测),体视显微镜观察发现样品整体呈粉红色,透明度较好,有大量鳞片状矿物定向排列,少量黑色金属矿物,样品裂隙发育并有紫红色胶结物沿裂隙分布或呈团块状,团块内可见气泡及黑色不透明包裹体。红外光谱检测显示3039.26cm^(-1)胶结物特征峰且主体矿物为石英。根据透反射偏光显微镜下观察及扫描电镜能谱仪检测,紫红色粒状物为有色胶,粉红色片状矿物为白云母,黑色短柱状矿物为金红石,及少量钾长石、锆石、磷钇矿。综合检测结果发现,这是一种在天然石英岩玉中注胶,用于改善“草莓晶”颜色的充填处理品。该类处理品具有一定欺骗性,检测时应特别关注对包裹体的放大检查及红外光谱特征。Recently,a new type of"strawberry crystal"quartz rock jade filling treatment product appeared on the market,the filler is to the red mineral inclusion,the basic gemstone refractive index meter detects its refractive index as 1.54(dot test),the stereo microscope observation that the sample is overall pink,the transparency is good,there are a large number of flake-like minerals arranged in a certain direction,a small amount of black minerals,the sample has a developed crack,and there is purple-red cement along the crack distribution or in a blocky shape,and there are bubbles and black opaqueclusions in the block.Infrared spectroscopy detection shows that the characteristic peak of the cement at 3039.26 cm^(-1)and the main is quartz.According to the observation under the polarizing microscope and the detection of the scanning electron microscope energy spectrum,the purple-red granular material is colored glue,pink sheet-like mineral is muscovite,the black short columnar mineral is rutile,and a small amount of potassium feldspar,zircon,andazite.According to the comprehensive detection results,it is found that this is a filling treatment product that is injected with glue in natural quartz rock jade to improve the of"strawberry crystal".This kind of treatment product is somewhat deceptive,and special attention should be paid to the magnified examination of inclusions and infrared spectro characteristics during detection.
