寿山石是我国最负盛名的工艺雕刻石。以X射线衍射和红外光谱测试证实，寿山石的主要成分分别为高岭石族矿物、叶蜡石和伊利石．其中以高岭石族矿物，特别是地开石及地开石和高岭石的过渡矿物占大多数。研究表明，不仅寿山石中的极品田黄石存在珍珠陶石。而且在原生矿高山石鸡母窝品种也发现了珍珠陶石。

On the Mineral Constituent and Characteristics of Shoushan Stone

The Shoushan stone (agalmatolite) is one of craft carving stones with great reputation in China.The testing results of the X-ray diffraction and inf ra red spectrum show that the major composition of Shoushan stones is composed of k aoline minerals, pyrophylite and illite, in which the kaoline minerals, particul arly dickite and dickite's and kaolinite's transition minerals, are in majority . The analysis results indicate that the nacrite is discovered not only in Tianhua ung stone ( the highest-grade Shoushan stone) but also in the Jimuwo stone ( o ne of ordinary Shoushan stones) which is derived from the primary ore of the Shous han stone.
