Summary:The Ezine region is located in the northwestern part of Anatolia where young granitic and volcanic rocks are widespread and show close spatial and temporal association. In this region magmatism began with the Kestanbol granite, which intruded into metamorphic basement rocks, and formed contact metamorphic aureole. To the east and southeast the pluton is surrounded by hypabyssal rocks, which in turn, are surrounded by volcanic associations. The volcanic rocks may be divided into two main groups on the basis of their lithological properties. Lavas and lahar deposits dominate the northern sector while ignimbrites dominate the southern sector. The ignimbrite eruptions were formed partly coevally with the plutonic and the associated volcanic rocks during the early Miocene. They appear to have been associated in a caldera collapse environment. Geochemical properties of the plutonic and the associated volcanic assemblages indicate that the magmas are hybrid and co-genetic and, were formed from a similar mantle source, under a compressional regime prior to the opening of the present E-W-trending graben of the Aegean western Anatolian region.
