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.
