芙蓉石内纤维状包裹体的研究现状

国内将粉色的水晶统称为芙蓉石,国外学者提出粉色的水晶可分为两类:粉石英和蔷薇石英,以晶形、颜色稳定性、包裹体等因素区分,其中无晶形、内部大量纤维状包裹体的蔷薇石英较为常见,可认为市面上见到的成品芙蓉石均为蔷薇石英.本文阐述了近年来国内外学者对芙蓉石的研究,客观地总结了对其内部包裹体的研究现状.金红石常作为包裹体出现在水晶中,芙蓉石内的针状、纤维状包裹体也被认为是金红石,但近年来的研究显示,包裹体的谱线匹配为蓝线石或类似物,并非金红石;不同的观察手段显示包裹体不同的分布特征和对称程度,指向不同的形成原因——先成或出溶,与六射星光的位置关系有待确定;另有学者通过实验证明,粉色纤维状包裹体对芙蓉石的颜色有明显贡献,且未发现经常被归为致色成因的色心及Ti/Mn元素.因而可认为,芙蓉石内部的纤维状包裹体为粉色蓝线石,遍布整体的包裹体造成了星光及粉色,但包裹体与星光的位置关系及成因有待后续研究.

Research Status of Fibrous Inclusions in Rose Quartz

Quartzs with pink color are called "FuRong stone" in China, while some foreign scholars think they should be divided into two categories: rose quartz and pink quartz, distinguished by crystal shape, color stability, inclusions and other factors. The most common finished FuRong stone is rose quartz, which is amorphous and contains hundreds of fibrous inclusions. In this article, the researches of rose quartz in recent years are expounded, and the research achievements of inclusions are summarized objectively. Needlelike and fibrous rutile are often found in quartzs as inclusions, but experimental data show that the fibres in rose quartz are dumortierite or something similar, not rutile;different means of observation show the different distribution and symmetry of the inclusions, indicating the different origins protogenetic or exsolved, and position relationship with six-ray asterism remains to be determined;some scholars have proved through experiments that the pink fibrous inclusions have obvious contribution to the color of rose quartz, and no color center or Ti/Mn element that is often classified as the cause of color. Therefore, it can be concluded that the fibrous inclusions in rose quartz are pink dumortierite, which cause starlight and pink, and the location with asterism and the origin of inclusions need further study.
