Abstract

Obsidian samples from several volcanic fields located in eastern Anatolia (namely: Nemrut Dagl, Siiphan Dagl, Meydan Dagl, Kars, Erzurum, Pasinler, Sankami§, Muj, Bingol), have been dated by the fission track (FT) method. Geological maps showing the volcanics studied in this work have also been compiled. These maps as well as the FT ages shown in this work (from 0.03 Ma up to 6.9 Ma), represent a solid contribution towards the understanding of the obsidian bearing volcanics of eastern Anatolia. Young dates (< 1 Ma), in agreement with published measurements, were determined on the west and north coasts of Lake Van. Obsidians distributed along an ideal arc extending from NE (Kars) to SW (Bingol) gave Upper Miocene-Pliocene ages. Two previous K-Ar ages only were available for the latter outcrrops; several of them were only very recently recognised.
