Fault is a kind of break which happens due to pressure on the crust and following the displacement of layers. It has different forms (Shayan, 1997, P.128).
The study area is located in Azarbaijan Sharqi, Northern and North Eastern Tabriz. It borders Tabriz plain in South and South East, and Aji chay main basin, Khaje and Shirinje Daghi in North. Due to slight activity of Northern fault system in Tabriz, geomorphologic forms are consequently affected by such activities like landslide in hillside, or landslide in different surfaces and scales. The present article aims to study geomorphology of Northern Tabriz fault which is in constant natural interaction with Tabriz city. Fault line scarps with steep slope is a dominant characteristic of the area. The main area in the study is 67 km2 and the highest point with 1900 m altitude is located in ‘Un ibn ‘Ali elevations and central part of the study area.
It should be noted that ‘Un ibn ‘Ali elevations which include the most important part of study area cover Northern and North Eastern sections of Tabriz plain, from Baghmishe in South East to Tabriz airport in North with a North West-South East direction. Furthermore, studies and investigations in different parts of this fault indicate the presence of different morphological traces caused by tectonic activities.
