Gabbroic complex of Soltan Abad is Located about 35 Km east of Sabzevar. According to tectonic classification, the study area is part of Sabzevar ophiolitic zone. The composition of these intrusion bodies are vary from gabbro to gabbro-diorite. The main minerals of gabbroic rocks are plagioclase (bytonite), clino-pyroxene and ortho-pyroxene (enstatit – hyperestene) and accessory minerals are ap...
This area is located in Derenjal Mountains, 60Km northwest of Tabas in central Iranian structural zone. The igneous rocks occur as plutonic with composition of olivine-gabbro, gabbro, diorite and monzodiorite in Kalshaneh Formation with Middle Cambrian age and as the extrusive rocks with composition of olivine basaltic lavas in lower part of Niur Formation with Silurian age. Petrographical and ...
BACKGROUND This study aimed to determine the effect of hardness change according to penetration depth in the laser fusing zone and observed the correlation of the microstructure as an Nd:YAG laser was irradiated to Ni-Cr alloy for dental use by setting the spot diameter size with respect to defocusing distances. In all groups, the hardness depth profiles in the laser fusing zone and heat-affect...
in this paper, an interval approach is presented to achieve perfect selectivity and maximum sensitivity in distance relay zones, considering uncertainties. for this purpose, first, the uncertainties affecting the settings of the three zones of a distance relay are discussed. then, by using the monte-carlo simulation, the uncertainties are modelled and the impedances seen by the distance relay a...
Taknar mining district is located about 28 Km northwest of Bardaskan in the central part of Taknar zone. Taknar Zone is surrounded by Rivash fault in the north and Dorouneh fault to the south. At least 30 percent of Taknar Formation (Ordovician age) is made up of submarine volcanic rocks. Geological evidence indicates that Taknar Zone displaced from another place to present location. Major str...
background priority setting in healthcare is a key determinant of health system performance. however, there is no widely accepted priority setting evaluation framework. we reviewed literature with the aim of developing and proposing a framework for the evaluation of macro and meso level healthcare priority setting practices. methods we systematically searched econlit, pubmed, cinahl, and ebsc...
واحدهای سنگی کرتاسه بالایی تا پالئوژن زیرین در استان خراسان جنوبی (شرق لوت) گسترش دارند. در این مطالعه پنج برش چینه شناسی سیلک، آرک شمالی، بین آباد، آرک جنوبی و کبوده به منظور ارائه مدل رسوبی نمونه برداری و مورد بررسی قرار گرفتند. در مجموع 26 رخساره در تمام برش ها شناسایی گردید که در جایگاه های مختلف یک پلتفرم کربناته از نوع رمپ از مناطق ساحلی تا رمپ خارجی نهشته شده اند. علاوه بر این برای برش ه...
The Piranshahr ophiolitic complex is located in NW Iran, and at north west of the Piranshahr town. Tectonically, the NW Piranshahr ophiolitic complex is severely mélanged and the boundary of different units in this complex is undistinguishable. Piranshahr ophiolite includes ultramafic, mafic, sedimentary and metamorphic rocks. Mafic rocks with basalt and diabase compositions are exposed in seve...
