Özet

In this paper, we present the preliminary data on the age of the radiolarian cherts deposited on top of basalts belonging to the Eastern Ankara Melange (part of the Izmir-Ankara Melange). Petrological studies on the basalts were carried out in order to constrain the tectonic setting of the studied basalt-chert sequences. Nine sections were sampled East and Northeast of Ankara and twenty seven samples were collected for biostratigraphic and geochemical analyses.
