摘　　要：鉴于绢云母(和白云母)类粘土矿物对于研究与矿化紧密相关的中低温热液蚀变机制、与温压有关的地质成因过程等的重要意义,开展了绢云母的岩矿光谱特征变异分析和成像光谱矿物识别,并对岩石、矿物的试验室光谱和影像光谱所反映的地质成因信息的提取进行探讨。Some kinds of clay minerals such as sericite and muscovite are of great significance in determining the hydrothermal alteration mechanism and the change of geological environment related to temperature and pressure. Variations of spectral features of rocks and minerals in the Hongtan gold deposit were analyzed, and minerals were identified using imaging spectroscopic data obtained from the Huangshan Cu - Ni deposit in East Tianshan Mountain of Xinjiang. This paper also discusses the extraction of geological genesis information, which is implied by laboratory mineral and rock spectra and imaging data.
