Zagros Mountains in west of Iran are covered by unique forests and rangelands. Increasing population, low level of development and high dependence of local people on natural resources for primary livelihood needs resulted in degradation of Zagros forests and rangelands. Along with these factors, since the last decade, climate change including severe drought is an important issue in the world, p...
Niabad-Qalaje ophiolitic complex is part of Sarvabad ophiolites in Kurdistan that exposed in northwest of Iran and the north of Kermanshah Ophiolites. The complex located in north of Zagros orogeny, consists of lens form, tectonically dismembered ophiolitic sequences located along the main Zagros trust. The ultramafic part includes serpentinized dunite and wherlite, serpentinite and chromitite ...
The Kermanshah ophiolite complex is a part of the Mediterranean–Zagros–Oman Tethyan ophiolites, located in the structural–tectonic zone of western Iran in the northern part of the Zagros main thrust. Doleritic sheeted dykes are well exposed within the ophiolite in the south of Sahneh. These dykes contain high MgO, Na2O, low TiO2 (2O5, and K2O contents, and high FeOt/MgO and LILE/HFSE ratios. Th...
Metadon persicus Gilasian & Reemer sp. nov. is described, based on a single female specimen from the Zagros mountains in Iran. Morphological variation among the members of the genus Metadon Reemer and their distribution in the world are discussed. Photographs of the new species are provided. The subfamily Microdontinae represents a new taxon for southwestern Asia and the genus Metadon is report...
We map the lateral variations of P-wave velocity beneath Zagros collision zone in Iran down to 800 km depth by regional travel time tomography. invert 32,293 relative residuals from five temporary seismic networks across NW and central northern Iran, a large number permanent stations distributed over Iranian Plateau. A salient feature our model is ~225 thick lithosphere Zagros, almost twice as ...
one of the cultural characteristics of eastern zone at central part of zagros range during 3rd millennium bc and at early bronze age is the extension of the related habitats to yaniq culture (ancient city near abhar) in this region. within field study conducted in 2008 in the plains covering central zagros eastern side that is situated in alvan basin, we managed to identify more than habitats r...
[1] We use the GEOS-Chem chemical transport model to interpret observations of tropospheric ozone from the Tropospheric Emission Spectrometer (TES) satellite instrument in summer 2005. Observations from TES reveal elevated ozone in the middle troposphere (500–400 hPa) across North Africa and the Middle East. Observed ozone abundances in the middle troposphere are at a maximum in summer and a mi...
