Abstract

The objective of this paper is to discuss the stratigraphic chart of the Sergipe and Alagoas basins, considering tectonic aspects. For this purpose, a mega-regional analysis of quite a wide seismic network, integrated with gravitational and magnetic data, as well as analogies with other sedimentary basins, is used. In the first part, the tectonic-sedimentary evolution and the principal unconformities shown on the stratigraphic chart are discussed; in the second part, the possible occurrence of halokinesis in deep waters in the Sergipe and Alagoas basins is discussed, analyzing conceptual models and analogies with other sedimentary basins. Finally, a proposed tectono stratigraphic chart is shown, which includes the modifications discussed.
