Correlation between quaternary stratigraphy units in different geological zones of Iran

Abstract

Kaveh Khaksar* and Keyvan Khaksar

The Quaternary deposits have been covered half past of Iranian territory and in order to importance are alluvial, evaporate, eolian, beach sand, effusive activities, landslide-debris and glacial drift deposits. The late walachian minor events and pasadenian main pulsation vigorous were caused uplifting of mountains and subsidence of valleys. The Quaternary alluvial deposits have been composed of thick stratigraphic sediments, which formed by conglomerate, coarse gravels, boulders, pebbles, sand, silt and marls. Intervals of different stages have been distinct by changing in sedimentation. In the four distinguished areas of Iranian platform typically different, quaternary deposits had similar characters, which indicated mentioned factors influence contemporaneous all part of Iran. In the central part of Iran, the Quaternary and recent Formations are mainly presented by extensive gravel sheets, deposited saltwater, brackish-water and fresh water lakes (Lake deposits, Lut and Kavir deposits, Recent salts), and by Aeolian sand, loess occurs in the western foothills of the Alborz and in the western spurs of the Kopet-Dagh. In the north part of Alborz mountains, Mazandran-Gorgan plain has been formed by marine deposits.
