The Taba metamorphic belt (TMB) is one of four PanAfrican metamorphic belts of the Sinai Peninsula forming the northernmost extension of the East African Orogen. The TMB underwent two main phases of ductile deformation accompanied by a single metamorphic event.

East African Orogeny Wikipedia

Gondwana assembly. The notion that Gondwana was assembled during the Late Precambrian from two older fragments along the PanAfrican Mozambique Belt was first proposed in the early s. A decade later this continental collision was named the East African Orogeny, but it was also realised that this was not the simple bringing together of two halves.

PanAfrican orogeny Wikipedia

History and terminology. The term PanAfrican was coined by Kennedy for a tectonothermal event at about 500 Ma when a series of mobile belts in Africa formed between much older African cratons.At the time, other terms were used for similar orogenic events on other continents, i.e. Brasiliano in South America; Adelaidean in Australia; and Beardmore in Antarctica.

Abstract The TransSahara belt is one of the mobile belts formed during the Pan African orogeny that spans between ~870 and ~550 Ma. The TransSahara belt was formed as result of the collision between the converging West African craton, Congo craton, and the Sahara metacraton continental blocks. The belt, with major exposure in the Tuareg and Dahomeyan, consists of preNeoproterozoic basement
