The Miocene marls or calcareous clay of the southern Rif groove is one of the geological wealth of the two regions of Fez in Morocco. For greater industrial development in Fez regions the present study on calcareous clays was undertaken. Physical and chemical characterization of this clay was carried out before and after doping with MnO2 following various analytical techniques such as X-ray diffraction (XRD), scanning (SEM) and transmission electron microscope (TEM). The doping of the clays was done at different percentages (5%, 10% and 15%) of MnO2. The results of the mineralogical analysis of clays before and after this doping show that the peaks appear for pyrolusite. Further characterization of the nano clays by TEM before and after doping, indicated the different nano organization of these oxides in the clay matrix.
