Abstract: The area studied lies to the north of gulf of Antalya and to the SE of Lake Eğridir.The aim of the study is to find out the basic geological problems of the area lying between central and westernTaurus Mountains and the relation between middle and western Taurus Mountains.In the research area, the rocks are grouped as ` `Units" which are different from each other in stratigraphic andtectonic characters. These units are termed as Karacahisar unity, Oppiolitic Unity and Dulup Unity. All these units aretransgresively overlained by deposits of Miocene age.These units show similarites with the units found in the western Taurus Mountains by their tectonic and stratigraphic characters (Antalya nappes). They differ in tectonic style from central Taurus Mountains.
