翡翠中的包裹体及其品级的激光拉曼谱学研究

Studies on Fluid Inclusions of Jadeites and Their Appraisal Classes of Quality by Laser Raman Spectroscopy

翡翠中含有较少的包裹体。在显微镜下观察到淡翠绿色的、比较透明的、云雾状的翡翠有＜4μm的包裹体。包裹体由熔融包裹体和流体包裹体两个类型组成。在近代激光拉曼技术迅速发展和广泛应用的基础上，运用付里叶变换激光拉曼探针鉴定翡翠的真假、质地优劣以及质量等级。重点研究了翡翠中的包裹体及其质量等级的激光拉曼谱学。

Jadeite includes a few fluid inclusions. Light viridian, relatively diaphanous and Cloud like jadeites are found to contain fluid inclusions of less than 4μm under the microscope. The inclusions Itave two types: melt-inclusion and liquid-inclusion.Since the Laser Raman technique has been developed rapidly and is extensively applied,the FT-Raman microprobe is used to judge vhether jadeites are true or false and to determine their texture features and quality classes.This paper focuses on the Laser Raman spectrographic study on the fluid inclusions of jadeites and the jadeite quality classes.
