Sketch of a possible scenario for the interaction between the Yesilirmak river and the NAF.
i) Figure obtained by 75 km of left lateral offset along the NAF, starting from the present day setting displayed above. Before the NAF propagation took place, the Yesilirmak and Kelkit rivers have deposited a large amount of fluvial sediments along their courses, whose present remnants are mapped.
ii) When the elongation of the Yesilirmak reachs a certain threshold, the stream power decreases, which trigger river capture. The capture is enhanced by the presence of the Havza pull-apart lake whose mapped extension corresponds to the Havza-Ladik lacustrine deposits displayed above.
iii) After the river capture, the lake should recess, lacustrine sediments and the new course of the Yesilirmak should begin to be offset. A nickpoint delimiting tributaries flowing northward or southward would migrate upstream toward its present position near the Ladik Lake.
iv) Present day morphology. A rough match is found between the 20 km
offsets of the lacustrine sediments in Havza and of the Yesilirmak river in the Erbaa basin.

Total Offset in Erbaa pull-apart
The Erbaa pull-apart basin resulting from 10 km releasing step along the NAF. The Yesilirmak river valley may be interpreted to be offset 75 km by the NAF.
