![]() Pluton contains magmatic enclaves and syn- plutonic dykes of dioritic composition. Porphyritic and graphic-granophyric textures are common in these three rock groups. Based on the field and petrographic studies, three main rock groups distinguished in Solarya pluton K-feldspar megacrystalline granodiorite, microgranite-granodiorite and haplogranite. It is a N-S trending magmatic body covering an area of 220 km2,approximatelly 20 km in length and 10 km in width. Solarya pluton is an epizonal pluton which discordantly intruded into metamorphic and nonmetamorphic basement rocks of Triassic age. One of the major volcano- plutonic complexes, the Solarya volcano- plutonic complex is remarkable for its coeval and cogenetic plutonic (Solarya pluton), hypabysal and volcanic rocks of Early Miocene (24-21 Ma) age. The post collisional magmatic activity produced several volcano- plutonic complexes in NW Anatolia (Turkey) during the late Oligocene- Middle Miocene.
