【 摘 要 】

This study aimed at understanding the dynamics of the recent geologic evolution in the São Franciscoriver valley, State of Pernambuco. The applied methodology encompasses two types of analysis, a geomorphologicone based on the elaboration of a detailed map, identifying a morphostructural unit andtheir respective morphosculptures. The second analysis was a geochronologic one based on OpticallyStimulated Luminescence. The results pointed to the existence of two sets of eolian morphosculpturesshaped along the late Pleistocene, exhibiting depositional activity until the Holocene transition. Theapplied methodology proved quite satisfactory in this region which is still lacking paleoenvironmentaldata.
