Abstract

Segundo Van Andel et al. (1973), a Zona de Fratura de Ascensăo pode ser diferenciada das zonas de fratura equatoriais por ter sido formada em estágios tardios da evoluçăo do oceano Atlântico SuI. Contestando essa interpretaçăo, Palma (1989), com base na morfologia, nas direçőes predominantes e magneto-estratigrafia da crosta adjacente da porçăo assísmica ocidental e falba transformante da Zona de Fratura de Ascensăo, inferiu que essa implantou-se no início da ruptura e separaçăo dos continentes sulamericano e africano no Cretáceo inferior há cerca de 110 Ma.
