摘要

One of the main faults of the Central Iran is Davaran Fault system which holds right-lateral strike slip with a pressure component. Contemporary activities of this fault signify the continuity of stresses up to now. Davaran fault system has extended parallel to Davaran Mountains. Most of the drainage networks of this region are located on trend of faults. The faults of this region are classified to 5 groups. These groups include conjugated faults of Riedel and Anti-Riedel (R, R'), normal faults (T), faults parallel with the major fault (Y) and faults approximately parallel with the main fault (P). T Faults are normal faults with tension mechanism. By calculation of sinuosity (Smf) of northeast and southwest mountain fronts of the region and ratio of valley floor width of the rivers flowing in the region to their wall height (Vf), it is specified that this region is active in terms of uplift and tectonics. The rivers have deep valley. Tectonic activity in northeast front is more active than southwest mountain front.
