针对采自福建寿山地区的寿山石“月尾紫”品种进行了光学显微镜、X射线粉末衍射、拉曼光谱和扫描电子显微镜等仪器的系统分析测试。结果显示，“月尾紫”呈显微微晶结构，主要矿物组成为地开石，基质中可见大量的紫红色矿物赤铁矿。赤铁矿呈浸染状分布，是致使“月尾紫”整体呈现紫色的原因。由于赤铁矿本身色调和富集程度不同，导致“月尾紫”的紫色调有深有浅，同时由于赤铁矿浸染分布于地开石颗粒间，使得“月尾紫”呈现不透明状。扫描电子显微镜下可见地开石颗粒主要呈假六方板状，棱角清晰，厚度均匀，呈叠瓦状、书册状排列，能谱测试结果显示扫描电子显微镜下微米级球状矿物颗粒为二氧化硅。

This paper investigates the mineralogical characteristics of ＂Yueweizi＂（purple larderite） from Shoushan County, Fujian Province by using optical microscope, X-ray power diffraction （XRD）, Raman spectroscopy and scanning electron microscope （with energy dispersive spectrome- ter, EDS）. The results show that ＂Yueweizi＂ shows microcrystalline structure, that its main min- eral composition is dickite, and that there is a lot of purple-red hematite in the matrix. The purple colouration of ＂Yueweizi＂ is due tohematite. Because of the different amount of hematite, the purple colours have various saturations, and hematite also influences the transparency of the stone. The scanning electron microscope results show that the dickite particles appear as pseudohexagonal platy, have clear edges and almost the same thickness, and overlap with each other. The EDS test results show that the spherical particles are silicon dioxide.
