Abstract

In NW Anatolia, Eocene-Oligocene post-collisional magmatism is continued with long intervals. In this study, it is aimed to reveal the lithostratigraphic position and geochemical characteristics of volcanic rocks outcropping in the southeast of Lapseki (Çanakkale) in NW Anatolia. The magmatic rocks that compose the topic of this study can be classified lithostratigraphically into 6 different units in the region. In Eocene period, there are calc-alkaline Laledağgranodiorite and Beyçayır volcanics with andesite, dacite composition that are the intermediate character, and also Kızıldamvolcanics in characters of alkaline and basic character (basaltic trachyandesite, trachybasalt). Furthermore, in Oligocene period, the calc-alkaline volcanism starting with Dededağvolcanics with dacite and rhyolite composition in acidic-intermediate character has continued with Kırcalarvolcanics consisting of basalt and basaltic andesite, and Harmancık volcanics ranging from basalt to rhyolite. Çamyayla Pluton is intruded to Oligocene volcanics in the region. In this study, the geochemical data proved that magmatic units arein character of alkaline and calc-alkalinefor Eocene-Oligocene period. Alkaline lavas in the region are classified as high K and shoshonitic and calc-alkaline lavas have medium-high-K.
