The Mozambique Ridge is located in the southwestern Indian Ocean between
two Mesozoic ocean basins: the Natal Basin and the Mozambique Basin. The
Mozambique ridge is formed from several bathymetric plateaus rising to 3500 m from
the seabed. It is believed that the origin of the ridge is associated with its partial
separation from the outskirts of the African continent due to the activities of the Karoo
hotspot. Recent studies show that the northeastern part of the ridge is thinned
continental crust covered with sediments, and the southern part is characterized by a
large number of extrusion centers indicating increased igneous activity. Experimental
studies described in this work showed that the formation of the Mozambique ridge
occurred in the context of the destruction of the Afro-Antarctic continent with
structural heterogeneities in the lithosphere of the African continent and the influence
of the Karoo hotspot.
