Identification of ammonium-bearing minerals by shortwave infrared reflectance spectroscopy at the Esquel gold deposit, Argentina

The Esquel low-sulfidation epithermal vein deposit in Chubut province, Argentina, is hosted by a Late Jurassic bimodal arc assemblage. Shortwave infrared (SWIR) reflectance spectroscopy of vein samples using a band-held field spectrometer identified ammonium-bearing illite, jarosite, and adularia (b...
