Mineral and Whole-rock Geochemistry of the Kestanbol Granitoid (Ezine-Canakkale) and its Mafic Microgranular Enclaves in Northwestern Anatolia: Evidence of Felsic and Mafic Magma Interaction

The Miocene Kestanbol granitoid, in Ezine-Canakkale, Turkey, is one of post-collision granitoids of western Anatolia, which have been related to the the late Cretaceous collision between the Anatolide-Tauride platform and the Pontides. Magmatism began during the early Miocene, with coeval alkaline to calc-alkaline plutonism and volcanism, controlled by the regional tectonic evolution. The Kestanbol pluton intruded regionally metamorphosed basement rocks. Volcanic and volcano-clastic sedimentary rocks overlie the pluton, which is bounded in the west and east by major faults. The pluton is frequently cut by felsic and mafic dykes and includes mafic microgranular enclaves (MMEs) that are mixing products of coeval felsic and mafic magmas.
