Mössbauer study of the Fe mineralogy in two different Argentine soils

Two Argentine soils featuring different characteristics and compositions (mollisols and ultisols) have been studied by Mössbauer spectroscopy and X-ray diffraction. The first type has a weakly developed profile with a solum thickness of 40 cm; the Fe oxyhydroxides are present in low concentrations i...
