35th International Geological Congress – Northern Tanzania: Geotourism of the Gregory Rift Valley and Serengeti Plains including Active Volcanism

Many of the high plateaus that characterize the East African landscape, including the Serengeti Plains are underlain by crystalline rocks of the Archaean and Proterozoic Eras. The Basement complexes were subsequently subjected to repeated cycles of uplift and erosion that commenced during the break-up of Gondwana (Jurassic-Palaeogene) and continued intermittently into the Neogene. These ancient, uplifted and eroded terranes were then subjected to an additional phase of rifting during the Miocene that has persisted into the Holocene.
