Determination of the relative tectonics activity rate for Inehvarzan-Dalichai anticline by using geomorphic indices

The asymmetric ENE - WNW trending Inehvarzan - Dalichai anticline that is located in the East of Damavand city and on the East of Central Alborz. This anticline consists of late Precambrian - Paleozoic - Mesozoic sediments. North limb of this anticline is confined to the Dehnar - Mosha fault and southern branch of this fault. South limb anticline is limited to the several secondary faults. Morphotectonic investigations including geomorphic indexes, e.g. Smf, Facet%, Af, Vf, for determination of the relative tectonics activity class of this anticline are carried out. The analysis of these indices demonstrates that North limb anticline is more active than the South limb.
