摘要:
利用常规宝石学测试、显微镜下观察、红外光谱、显微激光拉曼光谱等对四川省凉山州和云南省保山市出产的南红玛瑙的矿物组成、结构、致色矿物等进行测试。分析测试结果显示:南红玛瑙具有较典型的放射状-纤维结构,主要化学成分为SiO2; 正交偏光显微镜下可见大量呈条带状分布的浑圆状红褐色矿物包体,点状致色矿物为铁的氧化物赤铁矿,裂隙中可见后期热液成因的方解石等; 由拉曼光谱散射峰数值可知南红玛瑙中的SiO2大部分以α-石英的形式存在,少量以斜硅石形式存在。
Abstract:
The mineral composition, structure and coloring minerals of the Nanhong agate in Liangshan, Sichuan and Baoshan, Yunnan, were tested by conventional gemological test, microscopic observation, infrared spectroscopy and micro-laser Raman spectroscopy. The analysis results show that the Nanhong agate has a typical radial-fibrous structure, and its main chemical composition is SiO2; under the orthogonal polarizing microscope, a large number of round red-brown mineral inclusions with a strip-like distribution are observed, and the point-like coloring mineral is iron. The oxide hematite, the calcite of the late hydrothermal genesis can be seen in the fissure; the Raman spectral scattering peak value shows that most of the SiO2 in the Nanhong agate exists in the form of α-quartz, and a small amount exists in the form of oblique silica.
