The Razei region in the northwest of Ardabil is considered a part of West Alborz-Azerbaijan. Rocks in this area were created by Eocene volcanic activities. These rocks range from andesite to olivine basalt. The common texture of these rocks is Porphyritic with microlithic matrix. The phenocrysts of these rocks are often clinopyroxene, plagioclase, and olivine. The texture is made of microlithic...

This paper presents evidence on Mesozoic inversion of basin bounding faults within the Taleqan-Gajereh-Lar Paleograben (TGLP) in Central Alborz Range. For this purpose, well documented stratigraphy data across the TGLP together with the new acquired structural data on the geometry and kinematics of the paleograben basin bounding faults are utilized. The TGLP has evolved through the Early and Mi...

in many seismological applications, the earth is considered as a perfectly elastic, homogeneous, and isotropic body. although this assumption is approximately valid, it is known that seismic waves pass through the real earth that is anelastic, inhomogeneous and anisotropic.  we consider four processes that can reduce wave amplitude, i.e.: geometrical spreading, scattering, multi-pathing, and an...

Climate is one of the many factors such as socio-cultural values, economics, materials,administrative factors and technology that influence architectural forms. The climatic solutions effecting on architecture,differ in various regions, cultures, time and technology. The climate of the province of Golestan plays an active rolein the formation and diversity of vernacular dwellings. This region i...

the alborz coal basin is located in northern part of iran. the coal deposits of shahrood in eastern alborz, zirab in central alborz and abyek in western alborz were studied as typical coalfields of the basin. shemshak formation which is the main coal-bearing sequence was formed during the triassic-jurassic in the basin. it consists of sandstone, siltstone, shale and claystone, which variedly al...

b a ckground: a two year seroepidemiological study was designed to find out the seroprevalence and risk factors ofcanine visceral leishmaniasis (cvl) among stray and owned dogs in tehran and alborz provinces of iran. me t hods: blood samples of  602 dogs living in  11  counties of  tehran and  alborz  provinces were  taken by venipuncture in 2008–2010. after separation of blood sera, anti-leish...
