Abstract

The most widespread blocks within the Cretaceous ophiolitic melange (North Anatolian ophiolitic melange) in Central Anatolia (Turkey) are pillow basalts, radiolarites, other ophiolitic fragments and Jurassic-Cretaceous carbonate blocks. The pillow basalts crop out as discrete blocks in close relation to radiolarites and ophiolitic units in Cretaceous ophiolitic melange.
