Determination of Relative Tectonic Activity Levels of Stream Basins in the Part of the North Anatolian Fault Zone between Tosya-Kargı-Kamil by Geomorphometric Methods

The east–west Kızılırmak River Valley rests on a fault line in the central part of the North Anatolian Fault (NAF) Zone that extends from Tosya to Kargı from southwest to northeast, between the Devrez River Valley and Kargı–Kamil. The side creeks connected to the main streams from the slopes in both...

description The east–west Kızılırmak River Valley rests on a fault line in the central part of the North Anatolian Fault (NAF) Zone that extends from Tosya to Kargı from southwest to northeast, between the Devrez River Valley and Kargı–Kamil. The side creeks connected to the main streams from the slopes in both segments cut the faults that make up the NAF Zone, mostly steeply. This reflects in the drainage system and basin morphometry. Tectonic activity levels of the stream basins were obtained by measurement of the reflection of relative tectonic activity on geomorphometric parameters in the field. In addition to lithologically homogeneous segments such as Mount Kös, segments with more complex lithology, such as the Ilgaz Mountains, have been factors affecting geomorphometric parameters. The effect of the Dodurga–Hacıhamza Fault Zone, which cuts the NAF Zone in the south and consists of normal faults with right-lateral displacement, is reflected in these parameters . The geomorphometric parameters obtained in the southern block of the NAF, especially in the stream basins on Mount Kös, indicate that relative tectonic activity is higher there.
