Application of DiamondViewTM to Identification of Tourmaline Filled by Organics
-
摘要: 目前主要通过放大检查和红外光谱分析等测试方法对有机充填碧玺进行鉴定,但它们在准确性和直观性方面还存在一些问题。为弥补现有方法的不足,利用DiamondViewTM荧光成像技术对有机充填处理的碧玺样品进行研究。结果显示,在DiamondViewTM下碧玺样品呈绿色或蓝色荧光,部分样品可观察到生长结构特征。分布于碧玺裂隙及凹坑内的有机充填物呈较强的蓝白色荧光,并与碧玺的荧光具有明显的差异和界限。利用DiamondViewTM荧光图像分析,可以快速准确地识别充填物的位置及分布,也为碧玺在充填程度等方面的研究提供了新的思路。

Abstract: Tourmaline filled by organics can be identified by magnification and FTIR techniques,but there are still some problems on its accuracy and visibility.In this paper,the DiamondViewTM observation technique is firstly applied to the study on the tourmaline samples filled by organics.It is found that tourmaline samples displays green or blue fluorescence when irradiated by ultraviolet fluorescence lamp with wavelength shorter than 230 nm in DiamondViewTM while those filling materials show different ultraviolet fluorescent features.And it is easy to identify the position and distribution of filling materials quickly.In addition,growth structures and other internal facts are observed in some samples under DiamondViewTM.DiamondViewTM not only offsets the deficiency of traditional test methods,but also provides possibilities to research on growth structure,position as well as identification of synthetics.And it can tell researchers to what degree tourmaline could be filled.-
