    Petrogenesis of the Late Cenozoic Egrigoz pluton in western Anatolia, Turkey: implications for magma genesis and crustal processes
    (Taylor & Francis Inc, 2008) Ozgenc, Ismet; Ilbeyli, Nurdane
    The western Anatolian magmatic province is typified by a large number of Late Cenozoic post-collisional granitoids. Of these magmatics, the Egrigoz pluton is one of the largest and least-understood plutons in the Menderes Massif. The Egrigoz intrusives are subalkaline, high-K, and calc-alkaline, and have characteristics of I-type granites. They consist mainly of granodiorite and granite. The intrusive rocks show enrichment in LILE and LREE relative to HFSE. Their chondrit-enormalized REE patterns are fractionated and have small negative Eu anomalies. Geochemical characteristics of the Egrigoz pluton indicate an origin through partial melting of mafic lower-crustal source rocks. In western Anatolia, the melt generation mechanism for the intrusive rocks could be crustal extension and uplift following collision.
