-İdiş Dağı-Avanos area is located
on the northeast of Nevşehir, and is a part of the Central Anatolian
Crystalline Complex. The basement rocks of the study area constitue? Mesozoic
aged Aşıgediği Metamorphics, that represent the uppermost unit of the Central
Anatolian Metamorphics and consist of platform type meta-carbonates. İdiş Dağı
Syenitoid, composed of quartz syenite, alkali feldspar quartz syenite and
quartz monzonite intruded the Aşıgediği Metamorphics, and generated contact
metamorphic zones. Karahıdır Volcanics are found as dykes cutting the İdiş Dağı
Syenitoids and as blocks in the Göynük Volcaniclastic Olistostrome. Göynük
Volcaniclastic Olistostrome unconformably covers the basement rocks. It is
formed within a fault-controlled extansional basin in Uppermost
Cretaceous-Lower Paleocene period, and includes the olistoliths of the
Karahıdır Volcanics and İdiş Dağı Syenitoids. The late Lower Paleocene-Upper
Paleocene Yeşilöz Formation consists of the Saytepe Conglomerate Member and the
Asaftepe Member and represents the terrestrial and lacustrine depositional
environment. Middle Eocene Mucur Formation characterising shallow marine
(reefal) deposition transgressively overlies the basement rocks. It is
suggested that in the Early Miocene, a compressional system effected the İdiş
Dağı Area, and the basement rocks were thrusted over the Tertiary cover units.
The neotectonic period started in Late Miocene in the study area. In this
period a new tensional system became effective, Ürgüp and Asarcık Formations
are deposited within the basins which are controlled by the Central Kızılırmak
Fault Zone. The Quaternary aged travertine occurrences and talus deposits are
also related to this fault zone. The Karataş Volcanics and Kızılırmak River
terraces of Quaternary of age are mainly controlled by the Central Kızılırmak
Fault Zone.
