Özet

It is proposed that Late Cenozoic N-S extensional tectonics in western Turkey began in the latest Oligocene-Early Miocene (similar to 24-20 Ma) and has been related to the spreading and thinning of an over-thickened crust (i.e. orogenic collapse) created by an earlier Palaeogene (similar to 65-22 Ma) compressional regime. The occurrence of N-S extension immediately after the cessation of the compressional regime is attributed to hot lithosphere in western Turkey as indicated by pre- and syn-extensional magmatic activity.
