The Tabriz Faultʹs Geomorphological Phenomena

The Tabriz fault, is a strike-slip fault, that stretches from Zanjan-Soltanieh mountains in Iran, to Ararat mountains, in Turkey. Along this fault, from Bostanabad to Salmas, are different geomorphologic phenomena that contain displaced and cutting floodways, height difference and forming of scarpment, fault valley, fault spring, natural pools, and Urumieh Lake. This lake is an important phenomenon of Tabriz fault activity. Urumieh Lake before forming, connected to Gotur Chay and Aras river by a channel. This channel, is in northeast of Salmas and in north of Urumieh Lake. these features determine Tabriz fault from Bostanabad to Salmas. The purpose of this research is about distinction of geomorphogical consists which were formed from Tabriz fault and especially the formation of Urumieh Lake. The method of research consists studying of satellite images, aerial Photographs , geological and topographic maps and field geology.
