Abstract
Mössbauer spectroscopy has been applied to the study of volcanic glasses and closely associated clay minerals which were carefully separated from the sediments of the Pampe Region, Córdoba, Argentina. The parameters of volcanic glass samples show the presence of a high content of Fe2+ in octahedral coordination and some Fe3+ in tetrahedral and octahedral coordination. No remarkable difference has been found with a “pure” volcanic glass sample taken as a reference. In the clay samples, the only clay mineral found was illite.
