The bulk mass of the intrusive rocks found in the surroundings of Agoren/East Anatolia is composed mainly of Kfeldspar, quartz and plagioclase. Moreover the minerals biotite, muscovite and rarely amphiboles are present as minor components and apatite, zircon, chlorite, sericite, tourmaline as well as titanite are found as accessory components. The intrusives can be defined as granites and qaurtzmonzonites by plotting within the QAP diagram. They show a clearly prealuminous character (A/CNK ratio > 1.1) and typical geochemical attributes of S-type granites. The distribution pattern of trace - and rare earth elements in various diagrams indicate that the initial magma was generated by collision processes and accompanyed crust thickening and consequently a partial melting of the underlying Akdag metamorphics and Hinis metaophiolites.
