Investigation of Neotectonic Activities and Geomorphological featueres of Tabriz main Fault

Faults as important tectonic factors are influnece on geomorphological landforms. The Tabriz fualt with 600 Km length from Zanjan-Soltanieh. to Ararat mountains is most important fault in the north western of Iran, what is recognizable in the satellite images. Derivated data and information of earthquakes indicated probility of event of intensive earthquakes in tabriz and neighbouring areas. Quantitative measurment indicators such as proportion longitudinal profile to reference profile,proportion between the width of vallies to average of the height and sinuosity of montain front ration indicated the active fault. Tabriz fault have horizental and vertical movements. Newest movement is horizontal and strike-slip. According to the last studies of Tabriz fault geomorphological contain horst, graben, overthrust, alluvial fan displaced, river teraces,displaced and cutting streams, scarps, meander, shutter ridges and others are in relation to the tectonic activities. Also formation of Tabriz fualt had indirect effects on magmatism,salty diapers, hot spring, mineral spring, mud volcano and etc.
