Abstract

Geological and geochemical characteristics of the Mid-Cretaceous olistostromal ophiolitic melange exposed in the southern part of the eastern Pontide magmatic arc indicates that it originally formed during the drifting stage of a back-are basin (Neotethys). This view conflicts with the popular idea that this ophiolitic melange represents a typical tectonic melange or an accretionary prism developed in the fore-arc of the eastern Pontide magmatic are by northward subduction of Neotethys or Paleotethys during the Cretaceous.
