... (Cruzeiro do Sul lineament) that extends from the Cabo Frio High towards the Rio Grande Rise, thus involving both continental and oceanic crusts. The Rio Grande Rise is associated with the east–west-trending fracture zones, which are characterized by several aligned magnetic anomalies in the southern Santos...

... by Gladczenko et al. 1997 . The divergent motions of the two microblocks created a SE trend for the opening of this basin, and produced the two Capricórnio and Cruzeiro do Sul NW-trending lineaments. This direction is oblique to the general east–west relative motion between the African and South American...
