Terminal Eocene geological events in Turkey.

It could be concluded that in the northern, central and southern as well as some parts of eastern Anatolia, the Late Eocene flysch sediments were uplifted, eroded and overlain disconformably by gypsum intercalated biogenic limestones, red beds and conglomerates of shallow marine to continental origin. The continuous marine sedimentation from Late Eocene to Early Oligocene in Turkey appears typically in the northern and southern edges of Turkish Thrace and in the borders of the Taurus Orogenic Belt. Eventually, throughout the country, these events occurred and are affected by the Alpine Pyrennean orogenic phase. In northern Thrace the E/O boundary can be easily followed along the foothills of the Istranea Massif. In this region the Nummulites gizehensis and N. fabianii bearing limestones and sandstones of M-U Eocene are overlain by N. intermedius and N. vascus - containing marly limestones of L. Oligocene age. -from Autho
