The Iranian Plateau is characterized by diverse tectonic domains, including the continental collisions (e.g. the Zagros and Alborz Mountains) and oceanic plate subduction (e.g. Makransubduction zone). To derive a detailed image of the crust–mantle (Moho) and lithosphere–asthenosphere (LAB) boundaries in some tectonically units of the Iranian Plateau, we used a large number of S receiver functio...

One of the evidences of erosion process in the arid regions is wind erosion. Relative flatness, poverty of the vegetation, the dominant winds and alluvial weak formation are the most important intensive factors of the wind erosion. These conditions are in the central regions and the coastal plain in the south of Iran and the enormous sands massive where have been formed, scatter are the result ...

fauna of the the aphid parasitoids at southern parts of the zagros submountains, and their host associations have been investigated. a total of 24 parasitoid species were identified in association with 30 aphids on 36 host plant species, representing more than 80 tritrophic associations (parasitoid-aphid-plant). aphidius avenae haliday is newly reported from iran. generally, the area of souther...

Geoheritage requires proper conservation and has significant importance for geoscience education at universities. Furthermore, its related potential needs to be evaluated. This study focuses on two textbook localities (these are parts of larger geosites) from the Cenozoic orogenic belts, namely Zagros Greater Caucasus. The novel, tentatively proposed approach aims general geological characteris...

The Mombi bauxite deposit is located about 160Km northwest of Dehdasht in the Zagros Simply Folded Belt. The bauxite deposit exhibits an ooilitic and pisolitic texture. It contains higher amount of boehmite than those of diaspore, hematite, kaolinite, and anatase. This study uses the geochemistry of immobile elements in order to calculate the mass changes that took placed during weathering and ...

Forests remain an important resource in Iran, as most of the livelihood activities local communities, especially semi-arid environment Zagros forests, are dependent on forest resources. The aim this study was to identify type and extent dependency. Semi-structured interviews questionnaires were used collect data from 170 households Central Zagros. Results show that using firewood for fuel non-f...

In northwestern Iran, magmatic activity occurred during three main intervals: The Cretaceous, Eocene, and Miocene-Quaternary. first two phases of are more consistent with arc-type magmatism on an active continental margin; whereas the last phase, which has calc-alkaline alkaline affinities, shows similarity to postcollisional magmatism. Magmatic belts mostly situated in northern eastern parts O...

In the present study, the main aim was the spatial evaluation summer rainfall of northwest of Iran based on30 stations in northwest of Iran during 30 years of statistical period (1985-2014). An attempt, using geo-statistical modeling by ordinary least squares (OLS) and geographically weighted regression (GWR) procedures, was also made. The results represented that the GWR model with higher S2, ...
