The Kermanshah Ophiolite Complex (KOC) lies in the structural – tectonic zone of western Iran in northern part of Zagros main thrust and is a part of highly dismembered Kermanshah – Panjvin Ophiolitic belt. The best outcrops of the sheeted and isolated dykes in this complex are present in south of Sahneh area. They are basic in composition. The geochemical studies show parent magma is in its in...
Precipitation is a climatic elements that have temporal - spatial distribution. In this research database of Global Precipitation Climatology Centre (GPCC) with a resolution 0.5×0.5 degree for 50 year is used, that was constituted with dimensions of 12800*600. Temporal data are on the columns and pixels (spatial data) located on the rows. The results show an increasing trend in spring and fall ...
The geographic distribution of Astragalus (Fabaceae) in Iran was analyzed using a database of 7606 georeferencedobservations. Astragalus occurs in all provinces of Iran, but 88% ofthe observations are in five provinces including Tehran, West-Azerbaijan, Esfahan, Kordestan, and Khorasan-e Razavi.Most species are rare and narrowly endemic: Thelargest distance between two observations of the same ...
Phylogenetic relationships of Iranian Acanthodactylus species were investigated using 1407 bp of mitochondrial DNA including 606 bp of cytochrome b and 801 bp of NADH dehydrogenase subunit 4 (ND4). Analyses done with maximum parsimony, maximum-likelihood, and Bayesian inference included 67 specimens from 27 geographically distinct localities in Iran. Our molecular results proposed three clear a...
The present study investigates the occurrence of wild grasses at Epipalaeolithic and aceramic Neolithic sites in the Near East in order to assess their role in subsistence economies alongside the emergence of cereal cultivation. We use Chogha Golan in the foothills of the central Zagros Mountains (ca. 11.7-9.6 ka cal. BP) as a case study, where the archaeobotanical data suggest the frequent exp...
The larger benthic foraminifera Gyroconulina columellifera Schroeder & Darmoian, 1977 (type-locality: Maastrichtian Aqra Formation of Iraq) is described for the first time from two sections of the Maastrichtian Tarbur Formation of the Zagros Fold-Thrust-Belt, SW Iran. New details on its wall microstructure are provided. The microfacies is represented by bioclastic wacke-/pack-/grainstones with ...
تپه ی کلنان متعلق به دوره ی مس و سنگ میانه است و در شرق استان کردستان واقع شده است. داده های به دست آمده از گاهنگاری مقایسه ای و مطلقِ این تپه نشان دهندۀ استقرار در آن از 4050 تا 3650 ق.م است. به دلیل نبود لایه نگاری محوطه های مس و سنگ در استان کردستان در مقایسه با سایر نقاط ایران، تپه ی کلنان در شهرستان بیجار لایه نگاری شد. در اینجا عاوه بر گاهنگاری نسبی و مطلق، گونه شناسی مواد فرهنگی نیز مورد ...

In Iran, studies of the transition from hunting and gathering to farming herding have focused on early developments in Zagros Mountains. Here, authors present new zooarchaeological data Hotu Cave, which throw light sheep/goat management domestication during Epipalaeolithic–Neolithic southern shores Caspian Sea. Gazelle dominate Epipalaeolithic levels, while are most abundant Neolithic. Large qu...
