Özet

The Tertiary post-collisional magmatic activity in NW Anatolia occurred after the Late Cretaceous to Early Tertiary collision of the Sakarya and Anatolide-Tauride blocks and the closure of the Izmir-Ankara Ocean. The magmatism resulted in coeval emplacement of granitic plutons and andesitic volcanic rocks along the IzmirAnkara-Erzincan Suture Zone (IAESZ). The Kestanbol Magmatic Complex (KMC) on the Biga Peninsula (W of the IAESZ), is one of the representative magmatic complexes in the Sakarya Zone situated north of the IAESZ. Monzo-dioritic (syeno-diorite) plutonic rocks show close relationships with dacitic, trachyandesitic and rhyolitic rocks in space and time which are characterized by enrichment in large-ion lithophile elements (LILE) and depletion in Nb, Ta, P and Ti, interpreted as reflecting an arc-related origin.
