【摘要】 绿帘透闪石玉是市场上发现的一种新品种,主体呈特征的黑绿色和黄绿色,商家称其为"青花玉"。采用薄片观察、电子探针、红外光谱等测试手段,对其矿物学、宝石学、谱学特征进行研究,结果显示,其矿物成分主要为透闪石和绿帘石,并含有石英、方解石、绿泥石、褐铁矿、榍石等少量矿物,因此定名"青花玉"是不恰当的,建议定名为"绿帘透闪石玉"。其结构致密,硬度高,是一种较好的玉石材料,以特征性的颜色和结构易与其它玉石相区分。更多还原

【Abstract】 Epidote-tremolite jade called "Qinghua jade" by the seller is a new species in the market,whose main color is black-green and yellownish green.By using thin section observation,electron microprobe and infrared spectra,we studied the mineralogy,gemological and spectral characteristics of this kind of jade.The results indicate that the main mineral composition are epidote,tremolite and the subordinate mineral composition are quartz,calcite,chlorite,limonite,sphene,so "Qinghua jade" is not the appropriate name.It is suggested that the name could be "Epidote-tremolite jade".It’s a kind of good jade material because of its compact structure and high hardness.It is easy to distinguish "Epidote-tremolite jade" from the other jade materials by the distinct features of color and structure.更多还原
