The acidic magmatism of the Menderes Massif developed in relation with Pan-African orogenesis is represented by augen-gneiss and meta-granites in the region. Existence of ort+bi+gr, pl+gr mineral assemblage in the augen-gneisses indicate that a medium pressure metamorphism took place in high-temperature part of amphibolite-facies. “Chlorite+ epidote” (kt + epi), “chlorite+ biotite+ muscovite” (kt + bi + mus) and “mus + bi + gr” assemblages formed in the augen gneiss and metagranite, respectively suggest that Main Menderes Metamorphism, which can be defined as a Barrow-type regional metamorphism in green schist-lower amphibolite facies conditions (5-8 kb pressure and 430 -550 ° C), took place in the area between Late Paleocene-Middle Eocene.

Presence of dark-colored enclaves with quartz diorite composition within the Pan African magmatics indicates existence of a mafic magmatism in the massif, distinct from basic one, mixed/mingled with felsic magmas. Postmetamorphic Gencellidere granite is a two-mica granite with a hypidiomorphic texture.
