Özet

The Kocali Complex in SE Anatolia is mainly composed of tectonically imbricated slices of pelagic rock suits (pelagic limestones, cherts, etc), platform carbonates, elastics, serpentinites and basic volcanics. It can be subdivided into four main parts as the Tarasa Unit, the Konak Unit, the Cilo Limestones and the Kale Ophiolite. In this paper, geochemical characteristics of basic volcanic rocks associated with pelagic sediments (radiolarian cherts, pelagic limestones, etc) have been studied along four stratigraphical sections (the Tarasa, the Bulam-2, the Korun-1 and the Korun-2) in the Konak and the Tarasa Units. The age of the volcanic sequences have been assigned to Late Triassic (middle Carnian to Rhaetian) based on the radiolarian data from the associated pelagic rock units.
