Conodonts of Khoshyeilagh Formation, the most complete section of Devonian rocks in the Alborz Mountains, northern Iran, has been studied, and subspecies of the genera Icriodus, Bipennatus, Polygnathus, Pelekysgnathus, Ancyrodella, Palmatolepis, Bispathodus, Scaphignathus, Clydagnathus, Gnathodus, Scaliognathus and Dollymae have been obtained from the studied section. The faunas indicate an Eif...

Dictyozamites barnardi sp. nov. and fakhri are the second third species of to be described from Iran Middle East. They derive Rhaetic Kalariz Formation (Shemshak Group) Ramsar area, Alborz Mountains, North Iran. is distinguished especially by short curved strongly falcate pinnae clearly auriculate bases particularly its long, slightly very elongated triangular pinnae, opposite sub position auri...

We studied the modern pollen rain in two different landscapes from Hyrcanian lowland forests up to slopes of Alborz Mountains Gilan province for first time. Pollen traps were installed one year and moss samples collected along altitudinal transects 100 1800 m 2300 elevations. The results counting environmental DNA barcoding (metabarcoding) compared 32 locations. In total, 81 vascular plant spec...

The aim of this study was the spatial and temporal monitoring soil erosion patterns in Iran. G2 model used, as an appropriate tool to provide required month-time step country-wide loss maps statistical outputs. input parameters were derived with field surveys remote sensing imagery (MODIS, SRTM, SPOT, Sentinel-2 scenes). An innovation for consideration snow cover effect on rainfall erosivity. I...

Abstract In the Gasht-Masuleh area in Alborz Mountains, gabbroic magma intruded Palaeozoic metasediments and Mesozoic sediments crystallised as isotropic cumulate gabbros. LREE enrichment points to relatively low degrees of mantle melting depletion Ti, Nb Ta relative primitive an arc related component magma. Clinopyroxene compositions indicate MORB signatures. U–Pb zircon crystallisation ages 9...

Visceral leishmaniasis (VL) or kala-azar mainly affects children in endemic areas. This study was conducted to determine the seroprevalence of VL using direct agglutination test (DAT) in children living in rural districts of Alborz Province located 30 km from Tehran capital city of Iran. Multi-stage cluster random sampling was applied. Blood samples were randomly collected from 1,007 children u...
