Résumé
The Mozambique Ridge consists of a north-south trending alignment of
large submarine plateaux lying parallel to the south-east coast of
Africa. During a recent cruise (MD 60/MACAMO, February 1989) 3,600 km
of seismic reflection lines and 3 dredge hauls were collected.
Precambrian metamorphic rocks (granite, gneiss or schist) and tholeiitic
basalts of Karroo affinity were dredged, indicating that the Mozambique
Ridge might be a continental fragment of Africa. In early Cretaceous
times, the ridge was segmented by transverse half-grabens that were
active during the transform motion of Antarctica and South America along
the Mozambique Fracture Zone.
