    The geological and structural studies of the Basement Complex rocks in Efon-Alaaye and Environ area revealed that the basement rocks has undergone polyphase deformation episodes leading to its structural realignment. The dominant rock types are the metasedimentary assemblages referred to as the “Efon Psammite Formation” and the older quartzo- feldspathic gneisses. Two phases of deformation have affected the entire study area. The first phase was characterized by intense deformation and folding accompanied by regional metamorphism. It is mostly a fabric forming deformation that also resulted in low angle plunge and mineral lineation development generally in the N-S direction, synformal, antiformal and overturned folds are typical of this deformational stage. Also, the development of associated fault to the Iwaraja (ductile) shear zone occurred during the second deformation .. Read More»
