the central alborz mountains of northern iran (figure 1) is a zone of intense active continental deformation and is the most heavily populated region of iran, including the mega-city of tehran with a population of over 10 million. the region is affected by numerous active faults, some of them having great seismic potential, and documented historical seismicity. hence, the central alborz is a pr...

The Duna Pb-Ba-(Ag) mine is located ca. 155 km north of Tehran in the central Alborz structural zone, northern Iran. ore mineralization occurs as stratabound, epigenetic, E-W and WSWENE trending veins veinlets fracture-controlled well massive open-space filling textures within a Permian dolomitic limestone host rock. Field observations mineralogical petrographic studies show dolomitization, sil...

Chlamydia is an obligate intercellular and Gram negative coccobacilli and one of the most important factors of abortion in ruminants especially in ewes. Purpose of this investigation Phylogenetic Analysis of Chlamydia abortus Isolated from fetus Aborted ewes of Alborz Province. In this study, of 100 aborted fetuses abomasum of 32 sheeps flocks were Alborz Province, DNA was then extracted IGS-Sr...

Active deformation in Alborz range is due to N-S convergence between Arabia and Eurasia. This paper provides geomorphic traces of regional deformation in NW Iran in order to characterize active faulting on major faults. Soltanieh and North Zanjan fault systems are involved in convergence boundary extent between South Caspian Basin and Central Iran. Soltanieh and North Zanjan faults are major re...
