The Late Cretaceous Artvin volcanic rocks (LCAVs) from the eastern Sakarya zone (ESZ) of NE Turkey are composed of mafic/basaltic (S1-catak and S2-caglayan) and felsic/acidic (S1-Kizilkaya and S2-Tirebolu) rock types that occurred in two successive stages: (i) first stage (S1: Turonian-Early Santonian) and (ii) second stage (S2: Late Santonian-Campanian). Clinopyroxene thermobarometric results point that the S2-caglayan basaltic rocks have crystallised at higher temperatures and under deeper crustal conditions than those of the S1-catak basaltic rocks.
