A idade dos evaporitos da plataforma continental do Ceará, Brasil e sua relação com os outros evaporitos das Bacias Nordestinas

Abstract

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. 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. -from English summary
