The metamorphic basement consists of the following lithologies in ascending order: sillimanite-garnet gneiss, sillimanite-garnet-kyanite schist, sillimanite-staurolite-garnet-kyanite schist, staurolite-garnet schist and garnet mica schist. Kyanite-andalusite pegmatoids which occur within the kyanite-bearing schists were formed in the course of the last major metamorphism. The metamorphic basement is overlain by the allochthonous units which are relicts of the Lycian nappes which caused the last major metamorphism during the Eocene-Oligocene time in Menderes massif. The age of the apatite crystals obtained from the pegmatoids are determined by the fission-track method. The cooling age of the apatite crystals ranging from the Early Oligocene to Early Miocene are in good agreement with the field observations in the study area and geological evidences relating to the Menderes massif. -Authors
