Özet

Western Turkey has been dominated by N-S extension since the Early Miocene. The timing and cause of this N-S extension and related basin formation have been the subject of much debate, but new data from the Bigadic borate basin provide insights that may solve this controversy. The basin is located in the Bornova Flysch Zone, which is thought to have formed as a major NE-trending transform zone during Late Cretaceous-Palaeocene collisional Tethyan orogenesis and later reactivated as a transfer zone of weakness, and which separates two orogenic domains having different structural evolutions.
