Arsenic Incorporation in Pyrite at Ambient Temperature at Both

Nov 21, 2016 - Based on the observation of natural hydrothermal pyrites, AsâI is usually assigned to the occupation of tetrahedral SâIsites, with the same oxidation state as in arsenopyrite (FeAsS), although rare occurrences of AsIII and AsII hav


Nov 21, 2016 - Here, we provide evidence from X-ray absorption spectroscopy for AsII,III incorporation into pyrite at octahedral FeII sites and for AsâI at tetrahedral SâI ..... Because this latter spectrum does not differ significantly from that
