澳大利亚蓝色蓝宝石的内含物特征

Inclusion Characteristic of Blue Sapphire from Australia

  • 摘要: 对澳大利亚蓝色蓝宝石进行包裹体特征研究,为其产地鉴别提供理论依据。运用Leica M205A自动显微拍照系统对澳大利亚蓝宝石特征包裹体的形态特征进行图像采集,采用激光拉曼光谱仪进行包裹体成分测试。结果显示,澳大利亚蓝色蓝宝石常具有明显的颜色分布不均现象,部分具有六边形色带,且普遍具有愈合裂隙和裂理。显微观察可见固相包裹体、管状气液包裹体、指纹状包裹体等形态包裹体,偶尔出现三相包裹体,部分包裹体以双晶形态出现。经拉曼光谱测试可确认的包裹体种类有锆石、金红石、锐钛矿、赤铁矿、铌铁矿、霞石、CO2

     

    Abstract: The main purpose of this study is to observe the abundant inclusions of blue sapphire samples from Australia and analyze the composition of inclusions and provide a theoretical basis for the identification of its origin.The Leica M205A microscopic camera was used to finish the image acquisition of characteristic inclusions in blue sapphires from Australia. Laser Raman spectrometer was used to test inclusion composition.The result showed that the sapphire samples generally had obvious uneven colour distributions, healing fissures and partings. Some samples have hexagonal ribbons. Microscopic observation showed solid phase inclusions, tubular gas-liquid inclusions, fingerprint inclusions, and occasionally three-phase inclusions.Specially, some inclusions occur in the form of bicrystals.The inclusions identified by Raman spectroscopy include zircon, rutile, anatase, hematite, niobite, nepheline and CO2.
