Abstract: Menderes massif rocks, outcropping in Selimiye and Beşparmak region, are composed of units formedat the interval of Precambrian to Triassic. Massif is composed of Beşparmak formation of Precambrian age, Kılavuz formation of Silurian age, Aktaş formation of Devonian to Carboniferous age and Anitas formation of Triassicage. Menderes massif, having different metamorphic facies, is of sedimentary origin. Beşparmak formation has beenmetamorphosed by Early Caledonian orogeny while other formations, Kılavuz, Aktaş and Anitas, have been metamorphosed by Early Alpine orogeny. There is angular unconformity between the Beşparmak and Kılavuz formations,whereas there are disconformities between other formations.
