Tanzania Craton

[1] The Tanzania Craton forms the highest part of the East African Plateau.

The volcanic area of this rift covers the surface interface between the Mozambique orogenic fold belt and the Tanzania Craton.

They were intruded by granites and migmatized in different events that date back to 2.9, 2.7, 2.4 and 1.85 billion years ago.

[1] The craton mainly consists of Archaean granitic complexes, but also includes rocks from the Dodoma System in the central area, and belts of greenstone to the south and east of Lake Victoria.

There was widespread intrusion of kimberlites in the Cretaceous Period, mostly in the part of the craton that lies south of Lake Victoria.
