This study aimed at understanding the dynamics of the recent geologic evolution in the São Francisco river valley, State of Pernambuco. The applied methodology encompasses two types of analysis, a geomorphologic one based on the elaboration of a detailed map, identifying a morphostructural unit and their respective morphosculptures. The second analysis was a geochronologic one based on Optically Stimulated Luminescence. The results pointed to the existence of two sets of eolian morphosculptures shaped along the late Pleistocene, exhibiting depositional activity until the Holocene transition. The applied methodology proved quite satisfactory in this region which is still lacking paleoenvironmental data.
