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...

earthquakes are a particular concern because of the serious hazard they present. the existence of seismicity patterns such as the foreshock and aftershock clusters, doughnut pattern, seismic quiescence etc show that the earthquake occurrence in the active tectonic regions is not random and clustering phenomena are obvious characteristics of these events in space and time. fractal analysis, as a...

One of the more intractable problems that archaeobiologists struggle with is how to characterise ancient subsistence systems when the plant and animal remains that we study are incommensurate in so many ways. Three examples from the upper Euphrates and Iran illustrate how changes in plant remains are associated with changes in animal exploitation. Two of them consider the agropastoral continuum...

Iran is known as the most complex and varied country in southwest Asia, in terms of geography, vegetation, climate and consequently biological diversity. The rather high number of recorded endemic species of Fulgoromorpha in Iran indicates a high potential for speciation in some areas. In this study, in order to identify the endemic zones for Fulgoromorpha of Iran, three main biogeographic regi...

the noorabad-kermanshah ophiolite is part of eastern mediterranean-zagros-oman tethyan ophiolites, that this area is located in south-southwest of the main zagros thrust fault. this ophiolite consists of peridotites, serpentinites and pegmatite gabbros as mantle sequence whereas crustal sequences are composed of locally layered gabbros, isotropic gabbros, sheeted dike complex, basaltic to andes...

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...
