激光拉曼光谱在岩矿鉴定中的应用

The Application of Laser Raman Spectroscopy to Rock and Mineral Identification

激光拉曼光谱以其非破坏性、高灵敏度和高分辨率等特性,一直以来都是研究矿物的重要方法之一。通过激光拉曼光谱及mapping扫谱,可准确、方便的获得矿物的成分组成、应力分布、蚀变情况等信息,了解矿物的变形、断裂机理以及矿物质的形成机理,恢复其成岩环境。

Rock-mineral identification is an important basis for geological research, and its precision, accuracy and degree of research have a direct impact on the regional geological prospecting work. But the results of identification are easy to be influenced by the size of the mineral, the optical change of mineral because of making sample, the experience level of appraisers and so on, with traditional method of optical microscope. The laser Raman spectroscopy is one of important methods of rock-mineral identification. It has many advantages, such as non-destructive, high sensitivity and high resolution. By laser Raman spectroscopy and mapping scan, mineral composition, stress distribution and alteration information can be obtained accurately and conveniently.
