ABSTRACT:
Base on geological history evaluation using
regional stratigraphy, sedimentary environments, magmatic activities, metamorphism
and structural trend in Iran, physiographic-tectonic zoning map of Iran’s
sedimentary basins has prepared. This map has prepared to point out the
basement tectonics role in Iran. It contains twenty-four different
provinces. Iran has composed from different plates: Arabian plate in
south and west, Cimmerian manipulated in north and east, Eurasian plate in
northeast margin. Cimmerian manipulated at least can be divided to the
smaller part, East-Central Iran and North-Central Iran microcontinents. There
are evidences for thick-skinned tectonics in the border zones of these plates and
microcontinents, especially in Sanandaj-Sirjan overthrust
belts that it formed by crustal stacking wedges. Also, Neoproterozoic-Phanerozoic
Tectonic column in the Arabian, Cimmerian and Eurasian plates under Iran
Country area have introduced.
