| 摘 要： | 采用薄片观察、电子探针、红外光谱等测试手段,对玛纳斯碧玉的各品种进行了矿物学、宝石学、谱学特征和化学成分的研究。结果显示,玛纳斯碧玉的主要矿物组成为透闪石-阳起石,其中翠绿色点状物"翠花"是由于早期阳起石而形成。玛纳斯碧玉的物质组成特征显示其为超基性岩蚀变而成。

| Abstract: | Mineralogical, gemological and spectral characteristics and chemical constituents of all kinds of green Manasi nephrite were studied by using slice observation, electron microprobe analysis and infrared spectra. The results indicate that the main mineral components are tremolite and actinolite and that the emerald green spotted structure "Cuihua" of Manasi green jade is formed from early actinolite. The material composition features indicate that green Manasi nephrite is a product of the alteration of ultrabasic rock. |
