Description
The Kaman-Kirsehir region intrusions were generated in a post-collisional extensional setting following Cenomanian-Turonian docking of an oceanic island arc, comprising the supra-subduction zone (SSZ) Central Anatolian ophiolite (CAO), onto the Tauride-Anatolide Platform (TAP). These granitoids have been named, from N to S, the Camsari quartz syenite, Hamit quartz syenite, Bayindir nepheline-cancrinite syenite, Durmuslu nepheline-nosean-melanite syenite porphyry and Baranadag quartz monzonite. They intrude the crustal metasediments of the Central Anatolian Crystalline Complex (CACC) and CAO and are unconformably overlain by Upper Paleocene to Lower-Middle Eocene sediments.
