Isparta Angle is one of the most important geographical structures in SW Anatolia developed by bending of Taurides in northern part of Antalya bay. The Eirdir-Kovada graben, which extends through N-S direction and diminishes towards the S, divides Isparta Angle into two equal sections. Mesozoic carbonate sequence forming the western part of Isparta Angle is called "Akseki-Anamas autochthonous". The autochthonous rock seqeunce forming the western part of Isparta Angle is called "Beydagları autochthonous ".
The structural entities within the Isparta Angle extends parallel or semi-parallel to main N-S trending lines. Although a great number of the folds located in the eastern part of Isparta Angle are generally NW-SE extensions, the folds located in the western part are mainly NE-SW extensions. However, the axis of folds in the northern part of Isparta Angle dominantly exhibit NNW, NNE and EW trendings. Due to pushing effects of E side of Isparta Angle towards W side until Early Pliocene along N-W Aksu thrust, multi-stage thrusts parallel to Aksu thrust are formed, especially in E side.
The geological structure known as Kışla dome is located on the N-S extension alkaline Afyon-Antalya volcanic trend. The volcanics consisting of trachyandesites, trachytes, phonolithes and lamproites formed mainly by sub-volcanic dykes, domes and pyroclastic tuffs extend along N-S alkaline volcanic trend within the Isparta Angle.
The most important distinguishing formations of the Kışla Dome are circular geometric structures, which are observed by satellite images and sophisticated radial drainage systems. The Kışla Dome is formed by the folding of Triassic and Tertiary formations in the area, and is surrounded by the Aksu thrust from E. The gravity and magnetic data measured on the dome structure range between -60 and -70 mgal and 46000 and 47150 nT, respectively.
The findings showing that no distinguishable anomalies are present on Kışla dome based on magnetic, gravity and heat flow measurements further indicate that this structure is not formed after magmatic activities and is probably formed after tectonic activities. The E-W thrusts and associated folding systems, which are developed between Middle Eocene and Early Miocene rocks on the north of Kışla Dome, show that the region was under the influence of N-S compressions during the Middle to Late Miocene. On the other hand, currently active N-W Aksu thrust surrounding the Kışla dome from E indicate that compressions developing in E-W direction are effective in the region from Pliocene to recent. Thus, it may be suggested that the compressions affecting the region from various directions from Middle Miocene to recent resulted in the formation of Kışla dome.
