The comparison of geomorphologic evidences of Gorgan and Neka Rivers near their estuary point into the
Caspian Sea represents different channel down cutting and depositional sequence, so that Neka River shows a
deeper down cutting near the estuary point, this research is seeking the reason of the difference. As a result, the
marine terraces were used as the geomorphologic indexes to show Neka River down cutting and coastal uplift
assessment. Totally there were 8 marine terraces identified by studying geological maps, satellite images and
outcrop investigations. 8 bivalve fossil samples were selected for carbon dating of the terraces. Afterwards the exact
position and elevation of terraces were measured and their topographic cross sections were drawn up to the coast
line. The carbon dating results show that tectonic forces did not act similarly in the eastern and southern parts of .. View More»
