Neotectonic activity and topographic manifestation of deep f aults at the East of the Caspian Basin

Abstract

Many deep regional faults at the East of the Caspian Basin (suggested by geophysical evidences) can be traced in the relief by some structural morphological features. It has been used for identification of new faults. The analysis of their neotectonic activity reveals that 80% of meridional faults and only 40% of latitudinal faults are active; the suggested explanation is primary significance of trans-meridional wave movements. The information on the neotectonic activity of the deep faults is important for oil and gas searches.
