Abstract
The Potiguar Basin is located in the equatorial margin of northeastern Brazil and presents several landform types related to a passive margin. These include features related to alluvial, eolian, coastal, and karst processes. In this context, compression that has affected the basin since the Paleogene has caused uplift, which is mainly observed in the central part of the basin and where a tectonic dome forms the highest elevated landform. Tectonic uplift has controlled the origin of several landforms, such as the karst landforms, fault-controlled valleys, the shoreline geometry, elevated sea cliffs, and alluvial-marine plains. The whole basin area now evolves under the influence of climate, eustasy, and neotectonics.
