新疆哈密绿松石的矿物学和光谱学特征研究

最近在新疆哈密发现了可规模开采的宝石级绿松石矿床。采用X射线粉晶衍射仪、激光剥蚀电感耦合等离子体质谱仪、扫描电子显微镜、傅里叶变换红外光谱仪、拉曼光谱仪、紫外-可见光谱仪等测试方法, 对该地绿松石的化学成分、矿物组成、表面微形貌、红外吸收光谱、拉曼散射光谱、紫外-可见吸收光谱等矿物学和光谱学特征进行了系统对比研究。新疆哈密绿松石的主要化学成分以富Cr (1 617 ppm), V (435 ppm), Ti (428 ppm), 贫Ba (99.9 ppm)为特征, 随着Fe2O3/CuO比值的递减, 绿松石的色调由绿变蓝。由磷酸根、羟基和结晶水引起的特征峰出现在该地绿松石的拉曼光谱和红外吸收光谱, 其中磷酸根的振动峰位于1 000~1 200和420~650 cm-1, 羟基的振动峰出现在3 400~3 600 cm-1, 而结晶水引起的振动峰位于3 000~3 300 cm-1。此外, 该地绿松石的紫外-可见吸收光谱显示, 在600~700和430 nm处分别有由Cu2+和Fe3+引起的吸收峰, 这两处的峰强与绿松石的蓝绿色调之间的关系, 和新疆哈密绿松石成分中Fe2O3/CuO的比值与颜色之间的关系对应一致。

Abstract

Recently, turquoise from Hami, Xinjiang Provence has been discovered with gem quality and large quantity. In this work, turquoise samples from Hami, Xinjiang were studied with X-ray diffractometer (XRD), laser ablation inductively coupled plasma mass spectrometer (LA-ICP-MS), scanning electronic microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), Raman spectroscopy (Raman), and ultraviolet-visible spectroscopy (UV-Vis) to obtain the mineralogy and spectra characteristics. The chemical composition of turquoise from Hami was characterized by rich Cr (1 617 ppm), V (435 ppm), Ti (428 ppm) and poor Ba (99.9 ppm). And, the color of turquoise gradually changed from green to blue with the decrease of the rate of Fe2O3/CuO. The SEM results showed that the turquoise crystals were mainly needle, columnar and long plate shape with the size of 0.2～3 μm. The infrared and Raman spectra of turquoise were induced by the vibration of phosphate group (located at 1 000~1 200 and 420~650 cm-1), hydroxy group (located at 3 400~3 600 cm-1) and crystal water (located at 3 000~3 300 cm-1). Besides, the UV-Vis spectra of the turquoise samples showed that the absorption peaks at 430 nm and 600~700 nm belonged to the electron transition of Fe3+and Cu2+, respectively.
