... of the regional Ugab and Uranus-Neuland Synclines; it is most likely correlative with the Mulden Group of the Otavi Mountainland. The Damaran regional structure of area is characterized by: D 1 an early phase of southward-directed gravity nappes ; D 2 the regionally dominant northeast-southwest to east-west...

The latter are interpreted as foreland basin deposits associated with collision between the Congo craton and the frontal magmatic arc of southeastern coastal Brazil ( Stanistreet et al., 1991 ; Cordani et al., 2003 ). The best...
