摘　　要：以危地马拉“乌鸡种”翡翠为研究对象,通过宏观特征观察、常规宝石学仪器测试、显微组织观察以及现代测试技术等,分析总结其宝石学特征。结果表明,危地马拉“乌鸡种”翡翠组成矿物以硬玉为主,含少量绿辉石。偏光显微镜下,黑色杂质分布在硬玉颗粒内、硬玉颗粒之间以及矿物微小裂隙内。红外光谱显示硬玉特征峰。在拉曼谱图中,样品黑色部分出现1366 cm-1、1594 cm-1石墨的拉曼位移峰。这些结果表明,危地马拉“乌鸡种”翡翠的黑色是由石墨类碳质导致的,属于原生色。本研究为建立危地马拉翡翠鉴定体系提供理论依据。In this thesis,the gemmological characteristics of Guatemalan"Black Chicken"jadeite was analyzed and summarized through macroscopic characteristics observation,conventional gemological instrument testing,microstructure observation and modern testing techniques.The results showed that jadeite was mainly jadeite with a small amount of omphacite as the main mineral of jadeite in Guatemala.Under polarizing microscopy,black impurities are distributed in jadeite particles,between jadeite particles,and in microscopic cracks in minerals.Infrared spectroscopy showed the characteristic peaks of jadeite;In the black part of the sample,the Raman shift peaks of 1366 cm-1 and 1594 cm-1 graphite appeared.The black color of jadeite is caused by graphite carbonaceous and belongs to the primary color.This study provides a theoretical basis for the establishment of a jadeite identification system in Guatemala.
