Salt Tectonic and its Geomorphical Manifestation in Azarbaijan Case Study: Salt Domes of North - West Tabriz

Salt domes are one of attractive landform in some regions. This phenomenon exists in different section of Iran. For example in Zagros, Qom, Semnan and Azarbaijan. As much as one-quarter of the Azarbaijan areas is underlained by Miocen evaporates beds(upper red formation).Where evaporate beds are thick, they have many important geomorphological consequences. Formation of salt domes Azarbaijan is related to many factors include halotectonism, halokinetic, magmatism and etc. Salt domes of Azarbaijan are distributed in four region (Miyaneh, north of Tabriz, west Mishou and Kharvaneh). From this region, salt domes of north Tabriz have many important geomorphological and environmental effects. Salt tectonics in this area have different concequences include the developement of salt domes, the production of folds and fault and associated drainage modification, the creep of salt as salt glaciers and widespread solution, subsidence and karst formation.
