The mineralogy of Mn oxides is highly variable and complex, since the number of minerals is large and the knowledge of their structures imprecise. In view of the scarcity of specific papers on Mn oxides in Brazilian soils and their unusually high contents in some soils of one of the Iron Ore Province (IOP) of Minas Gerais State, this study aimed to characterize the chemistry and mineralogy of these oxides in the soils of this region, stratifying them according to […]
