Trachyandesites, trachytes and latites associated with ignimbrite and pyrocalstic rocks, characterized by shoshonitic affinity are the main Plio-Quaternary volcanic rocks in the Sabalan region (Ardabil). Plagioclase, K-feldspar, biotite associated with clinopyroxene and glass are the main constituents of these lavas. Plagioclases are andesine to labradorite while clinopyroxenes have augitic com...
volcanic landform can be as terrain legacies from the past to the present era be considered. these heritage of land in terms of their unique characteristics can be considered as geomorphosite in the scientific community and the public. the evaluation of resources is one of the most important tasks of geotourism research.and thereby become profitable and thriving tourism industry in their own di...
The Ardabil geothermal area is located in the northwest of Iran, which hosts several hot springs. It is situated mostly around the Sabalan Mountain. The Sabalan geothermal area is now under investigation for the geothermal electric power generation. It is characterized by its high thermal gradient and high heat flow. In this study, our aim is to determine the fractal parameter and top and botto...
In order to evaluate seismic hazard along Qoshadagh Fault (QDF, the causative fault of 11 Aug. 2012 Varzegan- Ahar earthquake), geometric and seismic parameters of the fault were investigated. QDF consists of a central E-W striking, dextral-reverse segment terminating at both ends into NW-SE striking splay arrays. Both eastern and western splay arrays form locally transtensional bends. The NW-S...
The Qara Sabalan manganese deposit belongs to the Qara Dagh-Sabalan metallogenic zone and is located in the eastern part of this zone (north of Meshginshahr). Geology of the area include volcanic (pyroclastic) rocks and the small outcrop of sub volcanic bodies (quartz-monzodiorite) with Eocene to Oligocene age. Mn deposit is hosted within the trachyandesite and tuff. Mn mineralization occurs as...

condition of contour lines in topographic maps, explains more geomorphologic issues such as effective processes in the land forms found in nature. change in the curvature of the transverse profile of a valley in mountainous areas, the peak of the mountain range, also reflect the geomorphologic features and expresses the tectonic events and climate changes occurring in the region. these changes ...
in order to study adapatability and yield stability of irrigated bread wheat cultivars alvand, alamout, zarrin, navid, azar 2, sabalan, omid and bezostiya this experiment was conducted in rcbd during three cropping seasons (2007-2010) in six cities. simple anova and combined analysis of variance for three years in every location and also combined analysis of variance for three years and six loc...
the short arm of rye 1r chromosome (1rs) carries genes for resistance to diseases and pests. the presence of the 1rs arm also enhance adaptation, stress tolerance and yield potential of bread wheat. in the present study 17 bread wheat cultivars were screened to identify 1bl.1rs translocation (t1bl.1rs) by isoelectric focusing, c-banding and fluorescence in situ hybridization (fish) methods. iso...
