Mozambique Belt

The eastern portion has high-grade arc-derived rocks ranging in age from 841 to 632 million years ago.

[2] Many geologists consider that the Mozambique Ocean formed during the break-up of Rodinia between 800 and 700 million years ago, accompanied by volcanic activity.

Magmatism from this period is found in East Africa and Madagascar, although not in the southern Mozambique Belt.

According to a more recent theory, Gondwana formed over an extended period from accretion of independent terranes.

The Mozambique Belt rocks formed from magmatic underplating and a period of residence in the mid-lower crust followed by cooling between 640 and 620 million years ago.
