Balanced cross-sections across the Zagros fold–thrust belt in Iran are used to analyze the geometry of deformation within the sedimentary cover rocks, and to test the hypothesis of basement involved thrusting throughout the fold–thrust belt. Although the Zagros deformation front is a relatively rectilinear feature, the sinuous map-view morphology of the mountain front is a result of a 6 km stru...

allochthonous masses are common structures in zagros fold-thrust belt. they are generally considered as collapse structures formed by the influence of gravity and in rock units with competency contrast. however, large allochthonous masses mapped in dowgonbadan area in dezful embayment near the mountain front fault (mff) of zagros show characteristics different from the belt common collapse stru...

The aim of this work is to propose a first-order estimate of the crustal and lithospheric mantle geometry of the Arabia–Eurasia collision zone and to separate the measured Bouguer anomaly into its regional and local components. The crustal and lithospheric mantle structure is calculated from the geoid height and elevation data combined with thermal analysis. Our results show that Moho depth var...

medicinal species of mountain’s kelavs, scientifically named (kelussia odoratissmia mozaffar.) is an endemic species in iran. kelussia odoratissima is a perennial species and belongs to the umbelliferae. from the ancient times, the local and nomad societies had believed that the species traditionally have anti-ache, anti-inflation and anti-cough effects. seed and root of this species are boiled...

western and eastern populations of goitered gazelles are separated by zagors mountains as a barrier. bordering iraq, western population has suffered from drastic decline during and after iran-iraq war. presently, there are small numbers of the goitered gazelles left in the region with no clear understanding of their taxonomic status. it has been normally assumed that there should be a differenc...

In this paper the geometrical relationship of the folds which exist in the Folded Zagros Mountains, including Asef Mountain (northern Iran), were studied. The southern and western zones of the Zagros Mountains are called the Folded Zagros. These zones extend approximately 1,375 km in length with a width ranging from 120 to 250 km. Asef Mountain is located in northern Shiraz (from northern Sarda...

The authors propose that a heat-driven circulation from the Zagros Plateau has a significant impact on the climate of the Middle East Plain (MEP), especially summertime winds, air temperature, and aridity. This proposal is examined in numerical experiments with a regional climate model. Simulations in which the Zagros Plateau was assigned a highly reflective, “snowlike” albedo neutralized the h...

1. introduction mountains are the main sources of turbulence and change in the shape of atmospheric flows, and they can cause airflow upward as well as clouds formation and rain through productive mechanisms such as upslope condensation and convection. they also have an important effect on regional and world precipitation turbulence (banta, 1990; barros & lettenmaier, 1994), and can cause sever...

[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...

M ore than 7,000 years ago, when grapes and yeast joined forces for the first time to lift the spirit of humankind, the ancients imbibed with joy, unknowingly celebrating the beginnings of one of the world’s oldest biotechnological processes. The first “magical” juice came from spontaneously fermented grapes cultivated in the Zagros Mountains of Ancient Persia and the Caucasus Mountain Range be...
