【摘要】 以天然菱锰矿样品和市场新出现的菱锰矿仿制品作为研究对象,通过基本宝石学测试及傅立叶红外光谱及拉曼光谱对其进行研究与对比,结果表明:菱锰矿仿制品与天然菱锰矿可以通过光泽、荧光、条带形态等方面进行基本的区分,菱锰矿仿制品具有与天然菱锰矿完全不同的红外光谱与拉曼光谱,其中除了具有C-O振动外,还具有Al-O、H-O及有机物特征峰,经过光谱测试比对判断菱锰矿仿制品为水铝矿及方解石经过压胶结、染色形成。更多还原

【Abstract】 The natural rhodochrosite samples and newly emerging imitations of rhodochrosite in the market were studied and compared by the basic gemmological test and Fourier transform infrared spectroscopy and Raman spectroscopy.The results show that the imitation and natural rhodochrosite can be basically distinguished by the gloss,fluorescence and the shape of strip,and the imitation has the infrared spectra and Raman spectra which are completely different from natural rhodochrosite.In addition to C-O vibration,it also has characteristic peaks of Al-O,H-O and organic matter.By comparing the spectra,it is presumed that the imitation is formed by cementing and dyeing gibbsite and calcite.These features can be used to distinguish the imitation from natural rhodochrosite quickly and accurately.更多还原
