ABSTRACT: T index has been
calculated in the Chekene-Mazavand region in the NE Iran. This index shows
lateral tilting may be related to active tectonics. There are many streams and
transverse topographic symmetry factor has been calculated for all streams of
Kashafroud river. Firstly, based on digital elevation model, the study area was
divided into 28 sub-basins. Then transverse topographic symmetry factor was calculated
for each one. The values are between 0.14 and 0.57 and so, there are low,
moderate and high levels of relative tectonic activities. The areas with low
relative tectonic activities have found in sub-basinsno. 14, 15 and 24, moderate relative
tectonic activities have found in sub-basinsno. 2, 5, 6, 7, 9, 10, 13, 16, 18,
19, 21, 22, 23, 25, 27 and 28 and high relative tectonic activities have found
in sub-basinsno. 1, 3, 4, 8, 11,
12, 17, 20 and 26. The results show that theplains
have got low to moderate level of tectonic activity and faulted areas have got
high tectonic activity. This matter is compatible with its tectonic setting on
the Kopet Dagh belt in north east Iran.
