Lawrence, MA – May 31, 2016 – Quickly and accurately identify pathfinder minerals associated with high sulfidation epithermal deposits using an oreXpress field mineral analyzer and EZ-ID mineral identification software.
High sulfidation epithermal deposits are created by fluids from hot magmas. Neutralization of these fluids by rock produces mineral assemblages dominated by alunite, pyrophyllite, kaolinite, illite, and chlorite rich clays.
With an oreXpress high resolution/high sensitivity, full range field spectrometer and EZ-ID mineral identification software with the USGS and optional SPECMin libraries, a geologist can quickly scan outcrops, trenches, pits, and walls to gain valuable information for interpreting the type of alteration system and potential deposit. EZ-ID will match the unknown sample against known mineral spectra to provide a best choice with associated degrees of confidence. In addition, EZ-ID allows you to use match regions to focus on spectral features of interest to more accurately identify important minerals from mixtures. For example in high sulfidation epithermal deposits alunite can be identified by focusing on key absorption features at 1440, 1475, 1760, 2165, and 22320nm.
All oreXpress files are saved in ASCII format for easy import into 3rd party analysis software for mine planning, mineral mapping, and 3D imaging. With mineral identification accomplished in seconds, oreXpress allows a geologist to scan more area and collect more critical data for planning a drilling strategy that will maximize the return on investment. In addition, oreXpress files can become the basis for a digital archive of an exploration project/mine along with scans taken during core logging.
