Background: High concentrations of various heavy metals of mine tailings can easily contaminate the environment. Such materials need monitoring and remediation to prevent them from polluting the environment and food chain. Materials & Methods: The concentrations of certain metals were evaluated in the soil samples at Sorkheh and Mazraeh copper mining areas in northwestern Iran, using three r...
principal skarn deposits along the northern margin of the ahar batholith from west to east include mazraeh, vine and gowdoul skarn deposits. among these skarn deposits, the mazraeh cu-fe skarn deposit is the most typical skarn deposit in the nw iran. this skarn deposit is located 5 km. north of mazraeh village and 20 km north of ahar town. the origin and development of the skarn can be related ...
Mazraeh granidiorite is part of Shyvardag plutonic batholith which is located in eastern Azarbajan, 20 km north of Ahar town and 5 km north of Mazraeh Village. It is a part of Mesozoic –Tertiary igneous belt of the Sanandaj-Sirjan. From petrography and geochemical point of view, rocks are acidic to intermediate and the main part of the body is granodiorite. Texturally, the rock is mainly granul...

the qom formation, which hosts the mazraeh celestite deposit, contains dominantly limestones, marl and subordinate evaporites deposited in shallow marine environments. petrographic evidence indicates that the celestite deposits were formed by replacement of limestone. the presence of carbonate inclusions within celestite crystals as well as the pseudomorphic habits of some crystals suggests tha...
The emplacement of Oligo-Miocene age Sheyvardagh intrusive body within the older carbonate and volcanoclastic rocks is responsible for contact metamorphism and creating of Mazraeh deposit in epidote - garnet exoskarn of Western Alborz- lesser Caucasus metallogenic belt. Mineralogical paragenesis consist of magnetite, pyrite, chalcopyrite, bornite, covellite, hematite, goethite and malachite and...
This paper studies the shear zone of North Qazvin fault and investigates the location of rural settlements in this area. In selected sections, the presence of transverse valleys along the fault made it possible to investigate the evidence of shear zones in which we can see severe crushing in igneous rocks of andesitic and trachyandesitic type, and cataclastic. Moreover, traces of faulted and fr...
Background and Objectives: Cattle dermatophytosis (syn. cattle ringworm), an important skin infection, has received major consideration not only for economical losses in the animal breeding industry but also in regards to its zoonotic transmission to humans. For effective control measures, it is important to determine the disease prevalence in cattle herds. Materials and Methods: To determine r...
