Kütahya Grabeni'nin Tektonik Jeomorfolojisi (Batı Anadolu)
Özet
In this study, faults bounding the Kütahya Graben were divided into segments by criterias, age of fault, characteristics of fault, change of fault’s trending, being stepped, being crossed and offset by another fault. The analysis were conducted by using geomorphic indices through measureable morphological elements of basin and drainage systems occured depending on segments, relative activity among fault segments were assessed in consideration of results of analysis. Calculated geomorphic indices were mountain-front sinuosities (Smf: 1.06-1.92), triangular facets (Lf/Ls: 0.11-0.94), Valley floor width-to valley height ratio (Vf: 0.34-2.07), hypsometric integral (HI: 0.34- 0.48), hypsometric curve, asymmetry factor, stream length-gradient index and relative tectonic activity index. Results of analysis indicated that activity ratio of fault controlling the Kütahya Graben increases east to west. According to the results obtained from morphometric analysis, annual rise velocity of the Kütahya Fault Zone is more then 0.5 mm and tectonically active. As to the Parmakören, the Alayunt and the Karaöz faults, they are tectonically moderately active and annual rise rate are 0.5 mm to 0.05 mm. This shows that the Kütahya Fault Zone, south edge of the graben, is more active than faults on the north edges.
