    摘要:

    在大批量流通的寿山石收藏品中混有异常样品,本文在对其进行详细常规宝石学参数测验的基础上,进行了红外光谱与X射线能量色散荧光光谱仪分析,确定了矿物成分为水镁石。并在红外光谱测试手段的帮助下,确定了水镁石中常见碳酸盐次要矿物的种类。

    Abstract:

    Larderite is a precious material for sealing and carving. Having found some specimens similar to larderite in lots of larderite carving and ornament markets, the authors tested their refractive index, specific gravity and Mohs' hardness and examined their U-V fluorescence and characteristics under microscope and in hydrochloric acid. Nevertheless, the data obtained are not convincing enough to determine the mineral names of the specimens. Assisted by infrared spectra (strong and keen peaks at 3698 cm-1, wide bands in 3500~3400 cm-1 mean stretching vibration of—OH,the peaks at 560 cm-1 and 451 cm-1), the authors identified the specimens as brucite. The energy dispersion X ray fluorescence spectra (EDXRF) have also verified the conclusion.
