| 摘 要： | 以产自江西省婺源县的歙砚为研究对象，运用电子天平、显微硬度计、偏光显微镜以及X射线粉末衍射仪、环境扫描电子显微镜，对歙砚原石的宝石矿物学性质进行了较深入的研究，综合分析了歙砚的组成成分、质量分数及结构特征。测试结果表明：样品的平均摩氏硬度为4．45，平均密度为2．7485g／cm^3；其主要矿物为绢云母，呈细小鳞片状结构，定向排列，还含有石英、绿泥石以及少量的锆石、正长石、高岭石和斑铜矿等。环境扫描电子显微镜及其能谱仪的测量结果显示，歙砚样品的主要矿物为多硅白云母，其单晶颗粒好，呈叶片状、定向排列，其集合体呈叠瓦状结构分布；其平均化学式为K0．59Na0.50{（Al2．86Mg0．50Fe^3＋0.05）4．11-（Al0．91Si7．09）8O20]（OH）4}。
