Sericite herein refers to a group of white mica minerals, including muscovite, paragonite, phengite, and illite composed of a white mica mineral with the number of interlayer cations (e.g. Na, K) less than two per formula. Sericite as an alteration mineral is pervasive in the Luoboling porphyry Cu-Mo deposit; however only specific species of sericite are closely related to Cu-Mo mineralizations, which are hardly identifiable by naked eye,. Mineral mapping with near infrared spectroscopy is very effective in distinguishing species of sericite. In this study, a sericite spectral index is established, and an example for its application is present.
