Özet

Post collisional volcanic rocks cover large areas in the east of the Biga peninsula, Which is located in the NW Anatolian magmatic belt along the southern margin of Marmara Sea. These volcanic units span a compositional range from calc-akaline (i.e. andesite, dacite, and rhyodacite to rhyolite), to alkaline (olivine basalts) lavas. All rock units display coherent variation trends on the major and trace element Harker diagrams.
