Abstract
The several mud volcanoes have been exposed at the Gorgan area in the north Iran. The Garniarig-Tapeh is the biggest mud volcano and the investigation of its tectonic geomorphology is the main aim in this paper. Also, we have determinated tectonic and geologic setting of Naft-Lije mud volcanoes and several Salses as the exposed mud diapirs at Gorgan on the northern margin of Iran. These mud volcanoes have been formed during quaternary of as a shield shape hill or pool on the flat plain in coastal region SE Caspian Sea. There are flat area and several mud volcanoes that they have been triggered by buoyant driving mechanisms, have been appeared during dormant periods of mud volcanoes activity. This mechanism has been developed in neotectonic regime by convergent setting between The Cimmerian and Eurasian plates. Finally, the main characteristics of the Gorgan area have presented.
Highlights
Iran country has composed from the several physiographic-tectonic provinces
The Garniarig-Tapehmud volcano have got a shield shape with near to 25 meters height and near to 650 meters diameter and it has been formed on the flat quaternary plain in coastal region (Figure 3) of Caspian Sea
In central part of the Garniarig-Tapehmud volcano, radial streams have formed in a big pound that it has been filled by viscous clay (Figure 3)
Summary
Iran country has composed from the several physiographic-tectonic provinces. Each physiographic-tectonic province has a same structural trend and dominant mechanism of deformation, because these have related to tectonic settings, magmatic histories, stratigraphic variations and deformational models of crust. Mud volcanoes have been fund in the some parts of Iran. These parts are very important from the occurrence of petroleum point of view. The most mud volcanoes have been occurred along convergent plate margins where fluid-rich sediment is accumulated in deep-sea trenches at high rates. Such deposits enter the subduction factory, where liquids and volatiles are released due to increasing compaction stress and temperature
