The Role of Basement Lineaments in Formation of RecentMorphology(Formation of the Karaj and Chalus valleys

Category Tectonic & Seismotectonic
Group GSI.IR
Location 21th symposium on geosciences
Holding Date 24 May 2008

Abstract:
      Alborz range is making active tectonic environment in north of Iran. The longest lineament in the western central Alborz is coinciding with valleys of Chalus and Karaj Rivers that despite of their central displacement are located in same strike. On the basis of geological information, Aeromagnetic map, morphotectonic features and remote sensing data, an attempt has been made to show that valleys related to basement lineament and the beginning of their formation follow this lineament completely but later because of deformation, they displaced from first strike.
