云南兰坪富锶文石的发现及其研究

对发现于云南兰坪多金属矿床中的富锶文石进行了粉晶X光衍射、电子探针、显微硬度、折射率等测试，并通过电子探针成分和晶胞参数的变化分析，探讨了其晶胞参数变化的原因。在此基础上，对兰坪富锶文石的颜色成因进行了讨论，并对其作为宝玉石资源的利用优势及可能性进行了展望。

The discovery and study of strontianiferous aragonite in Yunnan Province

Strontianiferous aragonite occurs at the Yanzidong Cu deposit in the northern part of Lanping basin, Yunnan Province. Examination by such means as X-ray, EMB, test of microhardness and index of refraction together with gemological studies have revealed that this strontianiferous aragonite is a special kind of aragonite, the change of the crystal lattice and genesis of the colour have also been analyzed. In addition, the advantage and possibility of the application of the aragonite as a kind of gem have been studied.
