| 摘 要： | 寿山石是我国最负盛名的图章石。其矿物成分，最早人们认为是叶蜡石，近年来认为主要是迪开石、珍珠石。作者在寿山村的野外工作基础上，应用Ｘ射线衍射、红外光谱、化学全分析和电子顺磁共振等方法，重点对产于寿山溪周围的寿山石进行了矿物岩石学方面的研究。Ｘ射线衍射和红外光谱证实，寿山溪南侧和北侧的寿山石均是以迪开石等高岭石族矿物为主，而西侧的旗山则是以叶蜡石为主。研究表明，寿山石的外观特征与迪开石的有序度密度有

| Abstract: | Shoushan stone, the most famous agalmatolite in China, occurs around Shoushan Vi llage near Fuzhou, Fujian Province. People once considered shoushan stone to be made of pyrophyllite. Recently, many detailed studies about shoushan stone show that shoushan stone is composed of dickite and nacrite instead of pyrophyllite. Based on field investigation and XRD, IR, EPR and chemical analysis, the authors made mineralogical and petrographical studies in such aspacts as the mineral co mposition and the relationship between outh character and inner structure of sho ushan stone near the Shoushan River. XRD and IR studies show that shoushan stone on the northern and southern sides o f Shoushan River is composed of kaolin minerals such as dickite and nacrite, whi le shoushan stone on the western side of Shoushan River is composed of pyrophyll i te. This suggests that mineral constituents of shoushan stone are different in d ifferent places. Furthermore, the transparency of shoushan stone is closely rela ted to the degree of order of dickite: the higher the degree of order of dickite , the higher the transparency and the quality. Chemical analysis shows that the chemical composition of shoushan stone is similar to that of dickite, and the ex istence of Fe 3 in shoushan stone is responsible for its color. EPR studie s of shoushan stone also prove the existence of Fe 3 in its crystal lattic e, and demonstrate that the content of Fe 3 in the red part of shoushan st one is higher than that in white part. |
