Abstract The present paper discusses the geochemical affinities, origin and ages of Jurassic granitoids Sanandaj-Sirjan Zone (SaSZ) in eastern part Zagros Thrust Zone. A multidisciplinary, integrated approach was carried out using existing granitoid data (major, trace, rare earth element isotopes) knowledge regional geology (geodynamic metamorphic setting), coupled with geophysical (magnetic su...
Global solar radiation (Rs( on a horizontal surface in the estimation of evapotranspiration of plants and hydrology studies is an important factor. Average daily global solar radiation on a horizontal surface was estimated by artificial neural networks (ANNs) and five empirical models including FAO (No.56), Hargreaves-Samani, Mahmood-Hubard, Bahel and Annandale. The weather data was selected fr...
introduction frost as a harmful climatologic phenomenon affects various human activities and biological processes. due to mountainous nature of kurdistan province as the study area of this research in one hand and type and diversity of effective air masses on the other, the frequency, severity and duration of this phenomenon in the province are outstanding. confronting frost could be one of the...
the chadegan metamorphic complex is a wnw-ese- trending antiformal structure located in sanandaj-sirjan structural zone, iran.the inner core of the structure is made of orthogneiss, containing eclogitic lenses. schists and marbles lie structurally above theorthogneiss and crop out in the external limbs of the antiformal dome. two main deformational episodes have been documented in theschists an...
BACKGROUND & OBJECTIVES This study aims at studying mosquito-borne diseases as the major public health threat in Iran. Sanandaj outskirts are considered suitable habitats for mosquito larvae. In view of scanty reports on mosquito-borne disease implementation in this area, a study was undertaken to determine the mosquito fauna and frequency of mosquito larvae at Sanandaj City. METHODS In order...
attempts have been made to study the thermodynamic behavior of 1,3 butadiene purification columns with the aim of retrofitting those columns to more energy efficient separation schemes. 1,3 butadiene is purified in two columns in series through being separated from methyl acetylene and 1,2 butadiene in the first and second column respectively. comparisons have been made among different therm...
in this thesis protic and aprotic ammonium-based ionic liquids were synthesized and their surface tensions were measured in the range of 298-373k. the protics are alkyl ammonium-based ils with the carboxylate (formate, acetate, propionate) anion and aprotics are quaternary ammonium-based ils with bis(trifluoromethylsulfonyl)imide anion. capillary rise method was used for surface tension measure...
In the Kurdistan Province (west of Iran), manganese mineralization has occurred in several locations including Shahini (south west of Sanandaj), Sianaw (west of Mariwan), Tawakalan (west of Diwandareh) and Golchidar (east of Marivan), but Tawakalan mineralization has characteristics which cannot be interpreted by Petrological principles. This mineralization is located at the end of northwest of...

Pichagchi pluton is situated in the northeastern part of the Soursat complex in Sanandaj-Sirjan metamorphic belt of Iran. The pluton with the age of 74.20 Ma is composed mainly granodiorite, diorite, and tonalite in which mafic minerals are biotite and amphibole. In this study, composition of minerals used to describe the nature of the granitic magma and estimate the pressure and temperature at...
