Geotectonic Setting And Origin Of The Youngest Kula Volcanics (Western Anatolia), With A New Emplacement Model, Murat Tokçaer, Samuele Agostini, Mehmet Yilmaz Savaşçin

Turkish Journal of Earth Sciences

The Quaternary Kula volcanics are Na-dominant in character while all the older volcanic rocks of western Anatolia are generally definitive K-dominant rocks. As a unique example in western Anatolia, the existence of a huge amount of plateau basalts at Kula indicates rapid uplift of mantle material, as confirmed by new geochemical data. Based on our field observations, the oldest Kula volcanics are the plateau basalts with more than one main lava flow. At the beginning of volcanic activity (first-period plateau basalts), this plateau was vast. Subsequently, parts of the first-period plateau basalts were uplifted and partly eroded while other parts …
