Abstract: The rocks in the studied area consist of the metamorphic rocks of Menderes Massif and the Neogene aged sedimentary, volcano-sedimentary and volcanic rocks. The metamorphic rocks are unconformably overlain by the Neogene aged rocks. The rocks of Menderes Massif are represented by the following rocks : fine-grained sillimanite gneisses, the intercalated unit of the silDmanite-kyanite-staurolite-garnet schists, sillimanite-kyanite-staurolite-garnet schists and staurolite-garnet schists which contain muscovite-quartz schist interlayers, andthe marble with emery deposits. The pegmatoides investigated in the metamorphic rocks are classified in twogroups according to their mineral paragenessis as the kyanite-andalusite pegmatoids and the muscovite pegmatoids. Although the muscovite pegmatoids are observed in a wide-spread area, the kyanite-andalusite pegmatoids areonly found in the kyanite bearing schists. The kyanite crystals examined in the pegmatoids have been formed by aprocess of Al migration from the Al-rich country rocks during the metamorphism. The amount of kyanite in someof the kyanite bearing schists reaches economic concentrations. In the studied area, the metamorphie conditionsincreased from medium to high grade metamorphism.
