Abstract 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.
