The work deals with the "Geotectonic evolution of the Rapale formations". The geological and tectonic evolution of Rapale is the result of the influence of various East Pan African Rift events, Grevilian Orogenies, being outcropped by Rapale Gneiss. Rapale is filled with fragile regime structures such as faults, diaclases, veins, fractures, ductile regime structures such as Boudins, some lineations; high grain metamorphic structures such as migmatites (neosomes and palaeosomes), Grabens-type fault systems. These formations have a spatial orientation of between 179N and 250N (Nairuco, T'tchotcho and Nanahe formations), while in the case of Muhitho they extend up to 360N. These latter formations have undergone East African Rift events, and events that have yet to be identified are responsible for modelling the relief and spatial orientation of the formations.
