摘要
寿山石因主要产于福州北郊约30 km的寿山而得名。近年来,在我国国石的评选中,寿山石作为候选石名列前茅,其身价倍增。以红褐色系列寿山石样品为主要研究对象,采用常规的宝石学测试、X射线粉末衍射仪、傅里叶变换红外光谱仪对其矿物组成进行了较全面的研究。根据其主要矿物组成将该系列寿山石样品分为3类:高岭石族类、叶蜡石类和伊利石类。研究表明,可根据其相对密度值来确定寿山石的主要矿物组成,对其进行分类。
The larderite is named after Shoushan area located at northern outskirts of Fuzhou near 30 km. In recent years, the market price of the larderite has been rising steeply when the larderite is nominated for one of the national stones in China. In the paper, the mineral compositions of the reddish brown series of the larderite samples are generally studied by means of the conventional gemmological testing, X-ray powder diffraction and FTIR. According to the main mineral compositions, the larderite samples could be classified into three types, including kaolinite, pyrophyllite and illite. The results indicate that the main mineral compositions and sorts of the larderite could be confirmed by its relative density.
