| 摘 要： | 采用镜下观察、激光剥蚀电感耦合等离子体质谱、紫外-可见吸收光谱等观察测试方法,对缅甸和莫桑比克红宝石的常规宝石学、包裹体、化学元素含量及紫外光谱特征进行了系统的对比研究。结果表明,缅甸红宝石在紫外荧光灯下呈现较强的红色荧光,内部含有互为60°夹角定向排列的短针状金红石、"糖浆状"构造等特征包裹体,具有低Fe、高V、高Ga的微量元素特征,紫外区吸收截止边小于320 nm,且694 nm处的荧光较强。莫桑比克红宝石在紫外荧光灯下荧光较弱,内部可见双晶面、无序排列的金红石和角闪石晶体等特征包裹体,具有高Fe、低V、低Ga的微量元素特征,紫外区吸收截止边在350 nm附近。上述性质可用作区分缅甸和莫桑比克红宝石的标志性识别特征。

| Abstract: | Microscope, LA-ICP-MS, UV-Vis and other observational methods were used to perform the comparative analysis of conventional gemology, inclusions, chemical element content and spectral features of rubies from Burma and Mozambique. The results show that Burmese rubies exhibit strong red fluorescence under UV fluorescent light. They contain short needle-like rutiles, which are arranged at an angle of 60° with each other, and "syrup-like" structures. With the elemental features of low Fe, high V and high Ga, the UV-Vis absorption edge is smaller than 320 nm and the fluorescence at 694 nm is strong. Mozambique rubies have weak fluorescence under UV fluorescent light. Their characteristic inclusions are twin planes, disordered arrangement of rutile and amphibole crystals. With the elemental features of high Fe, low V and low Ga, UV absorption edge of Mozambique rubies is about 350 nm. The above properties can be used as original identification features of rubies from Burma and Mozambique. |
