Identification of ammonium anomalies by SWIR reflectance spectroscopy: Implications for mining exploration
The existence of ammonium anomalies in mineralized deposits in Argentina is presented. These anomalies are given by the substitution of potassium ion by ammonium ion in certain feldspars, clay minerals and sulfates. This substitution doesn't produce physical changes either in the minerals or th...
