Abstract: Study area is situated within the triangle of Bayburt - Erzincan - Aşkale, trending roughly in a NE-SW directionand mainly comprising of Liower Tertiary (Ypresian) turbidites (750-1000 m in thickness). It appears that these turbidites havebeen deposited by paleo-currents flowing mainly from SW to NE. Some turbidity currents were probably initiated by submarineslumps which started at the northern and southern edges of the basin, and moved downslope towards the axis where theyturned paralel to it and continued along the basin plunge towards NE.
