摘要："达碧兹"蓝宝石具有罕见的"核"+"六条臂"+"蓝宝石生长区域"的特殊结构。它的发现使"达碧兹"这一特殊结构跳出了种属的限制,具有更加广泛的意义。本文针对报道较少的"达碧兹"蓝宝石,运用现代光谱学中的X射线荧光光谱,微X射线束荧光扫描成分分布图以及拉曼光谱技术对其痕量元素种类及其分布进行了研究。将研究结果与前人对"达碧兹"红宝石的研究进行对比,指出了各种痕量元素特别是Fe元素的存在于"达碧兹"形成过程中的重要作用,并结合"达碧兹"蓝宝石形成的动力学及热力学因素,得到了"达碧兹"蓝宝石的形成是枝晶生长和层状生长交替进行的结论。
Trapiche sapphire has a rare texture of one core plus six arms and sapphire growth sectors. The existion in sapphire makes this texture out of species and also gives it a wider significance. Our research based on “trapiche sapphire” which has been relatively less reported. Modern spectroscopy technologies, such as XRF, XRMF and Raman have been used to test trace elements especially iron and their partitioning. The results have been compared with published data of “trapiche ruby” to show how trace elements especially iron play an important role during the texture formation. Kinetic and thermodynamic factors have also been considered and show a conclusion of that the formation of “trapiche sapphire” is carried out alternately by dendritic growth and layer by-layer growth.
