Geological Setting and Geochemistry of the Sürmene Area Basalts (Trabzon, NE Türkiye)
Abstract: The study area is located on t fie NE Zone of the Pontid Tectonic Unit. The basalts outcropping in the study area are observed intwo different levels as Liassic, and Upper Cretaceous age-levels. Tliere are distinct dissimalarities between them with regard to their petrographic and alteration character. The basalts of Upper Cretaceous age are c ale-alkali and the Liassic ones are tlioleiitic in composition.
