摘要
福建省质量技术监督局近日发布了福建省地方标准——地理标志产品寿山石(DB35/T 419—2012)。说明了该标准的起草和主要内容,并详细讨论了新标准中采用的寿山石分类方法,主要特征和鉴别方法。新标准中将寿山石分为田黄石类、高山石类、芙蓉石类和汶洋石类。其中,高山石类以高岭石族矿物为主要矿物,芙蓉石类以叶蜡石为主,汶洋石类以伊利石为主,田黄石类则是寿山石经过搬运埋藏的产物。相对密度和近红外光谱分析可以用来方便、快速地区分不同类型的寿山石。
The Fujian provincial bureau of quality and technical supervision recently published a provincial standard of the product of geographical indication-Larderite（DB35/T 419-2012）. This paper explains the drafting process and its key contents and it also provides detailed explanations on features of larderite and on classification and identification methods of larderite adopted in this new standard.
