Abstract
Two PETROBRAS oil wells drilled on the State of Ceara (Brazil) continental shelf (Mundau and Icarai sub-basins) reached relatively thick isolated evaporitic layers. Palynological cores and ditch samples analysis have positioned these salt beds within the Sergipea variverrucata Zone (P-270) and so time equivalent to late Aptian. According to palynological data and palynostratigraphical correlations, the gypsite layers that occur in the Parnaiba and Araripe basins, and the salt layers of Sergipe basin are equivalent in age to those of the Ceara submarine basin. However relative to the Paripueira salt (Alagoas basin) these evaporitic beds are younger.
