In this research, three alluvial Terraces that are located in pathway of Zayandeh-Rood River are studied. The river starts from Bakhtiayri Zardkoh mountain and after through Esfahan city ends to Gawkhony lake. Age of alluvial terraces is younger in upstream than downstream and the height level of the terraces decrease relative to current river bed toward the downstream. The terraces were sample...

Radar sensors obtain regular and frequent radar images from which ground motion can be precisely detected using a variety of different techniques. The interferometric synthetic aperture radar (InSAR) is utilized to retrieve the spatial characteristics of the largest coseismic landslide Maleh-Kabood, induced by the Ms 7.3 Azgleh earthquake in Kermanshah Province, Iran. The available seven interf...

Wildlife is an important biological indicator of viability of ecosystems, therefore, understanding habitat requirements of species is essential for biodiversity conservation. Determining the suitability of habitats for wildlife is important for effective management and conservation of species. The brown bear (Ursus arctos), as the largest carnivorous mammal in Iran, is distributed in most fores...

The Middle East region represents a key site within the Tethyan domain where continental break-up, collision, backarc extension and escape tectonics are kinematically linked together. We perform global mantle circulation computations to test the role of slab pull and mantle upwellings as driving forces for the kinematics of the Arabia–Anatolia–Aegean (AAA) system, evaluating different boundary ...

Lophotidae, or crestfishes, is a family of rare deep-sea teleosts characterised by an enlarged horn-like crest on the forehead. They are poorly represented in the fossil record, by only three described taxa. One specimen attributed to Lophotidae has been described from the pelagic fauna of the middle-late Eocene Zagros Basin, Iran. Originally considered as a specimen of the fossil lophotid †Pro...
