ABSTRACT: 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.
