The study area is located south of Nehbandan, in southern Khorasan Province. There are three mineralization zones with three veins in this area which number two is antimony rich and has anomaly for Au and Hg. This zone is composed of silica-carbonate with stibnite, pyrite, chalcopyrite and Fe-hydroxide. The textures of veins are open space filling, brecciate and colloidal. Mineralization occurr...
The Simorgh area is located about 113 km southwest of Nehbandan. Initial prospecting conducted by satellite data ASTER sensor with spectral angle mapper method, in order to identify probable alteration zones. The data, compared with field observations, have provided satisfactory results. This area consists of Eocene volcanic units in which various sub volcanic rocks have intruded in them. The m...
Based on field observation, magnetic data results and chemical analysis of the samples in the Haj - Elyas area northwest of Nehbandan, an iron ore body within the Lower Cretaceous dolomitic limestone, was identified. The intrusion of a Fe-bearing porphyritic diorite into the dolomitic limestone caused the occurrence of iron mineralization in the area. Studies of 750 meters of diamond drill Core...
خانه های سنتی نهبندان بیشترین سازگاری را با طبیعت و اقلیم دارند. معماران با طراحی صحیح و توجه به آسایش استفاده کنندگان توانسته اند در عین سادگی، پاسخگوی نیاز ساکنین خانه ها باشند. یکی از این فضاها، ایوان می باشد که در معماری مسکونی به شکل فضایی نیمه باز، جلوی اتاق ها قرار گرفته و با کاربری های متفاوت، دسترسی به فضاهای داخلی را ممکن می سازد. عنصر ایوان از ویژگی های بارز و به عنوان مهمترین بخش د...

background : this comprehensive study was conducted on multi-purpose one-humped camel ( camelus dromedarius ) sera and ticks to assess the epidemiological aspects of the crimean-congo hemorrhagic fever virus (cchfv) in northeast iran. methods : from may 2012 to january 2013, eleven cities were randomly selected in the khorasan provinces of iran as “clusters,” and at least 14 one-humped camels w...
bibi maryam granitoid body with about 5 km2 has intruded into ophiolite mélange complex in sistan suture zone, in east of iran. thermal effects of this body on the host rocks show that this activity occurred after emplacement of ophiolite mélange. this intrusive body with general northwest – southeast trend is mainly tonalite-quartz diorite but there is a minor unit as dykes of granodiorite in ...
The alkaline extrusive rocks of Neogene from Nehbandan-Assagie region, eastern Iran, include basanite, hawaiite, mugearite and benmoreite. Relatively low Ni and Cr contents and Mg-numbers of basanites are indicative of olivine and clinopyroxene fractionation from their relevant primary magma. Decreasing of CaO, TiO2, FeOt, HREEs and MREEs with increasing SiO2 indicate fractional crystallization...
Iran’s border villages are encountering with service deficiencies regarding social, economic and cultural dimensions. However, these entities are facing with foreign propaganda for enlarging border ethnic groups delimits and ignorance of these area’s capabilities and potentials. This in turn, requires more attentions toward bordering village. The major objective of this study is to investigate ...
