The Astaneh granitoid massif is located about 40 km to Arak city, central Iran, is a part of Sanandaj-Sirjan structural Zone. These intrusive rocks which are mainly composed of grnodioritic rocks, widely affected under hydrothermal alteration. The alteration zones, on the basis of field studies and mineralogy as well as the study of the REE behavior, are investigated in this paper. Eight altera...
results a total number of 20 out of 1772 (1.12%) examined students were found to be infested by lice. although the infestation rate was higher in girls, the difference of infestation rate between genders was not statistically significant (p > 0.05). the rate of head lice infestation was siginificantly (p < 0.05) correlated to their hair-washing behavior. parents’ literacy level also was siginif...
Pichagchi pluton is situated in the northeastern part of the Soursat complex in Sanandaj-Sirjan metamorphic belt of Iran. The pluton with the age of 74.20 Ma is composed mainly granodiorite, diorite, and tonalite in which mafic minerals are biotite and amphibole. In this study, composition of minerals used to describe the nature of the granitic magma and estimate the pressure and temperature at...
Gneisses of the northern part of the Zayandehrood Dam Lake, structurally, are located in the Sanandaj-Sirjan zone. The gneises with phengitic marble and metabasic bodies comprise a part of high-pressure units in the North Shahrekord metamorphic complex. Minerlogically, the rocks consist of quartz, garnet, phengite, k-feldspar, albite, tourmaline and rutile with zircon grains. Field (alternation...
Background and Aim: Road injuries and their consequences are one of the most important factors affecting health in all age groups. Considering the fact that the cities of Kerman province are located in communication route of the southeast, the aim of this study was to determine the risk factors for road accidents in intercity taxi drivers of Kerman. Materials and Methods: This cross-sectional ...
The granitic intrusives in southwest Saqqez are located in the northern Sanandaj Sirjan zone. These granites can be divided into mesocratic and leucocratic granites. The external morphology and internal structures of zircon from these granites have been investigated employing the classic Pupin method supplemented by electron microscope analysis. The zircon crystallization is a function of tempe...
The Anjir Khajeh area is located in the southern part of Sanandaj-Sirjan metamorphic belt in northwest of Golgohar iron mine. The rock units of the region include metabasites, metasediments, igneous and sedimentary rocks. Metasedimentary rocks containing mica-schist, garnet schist, and garnet staurolite schist, having metamorphosed into greenschist facies and amphibolite facies. Garnet mineral ...
The Chah-Bagh gold occurrence is located in Muteh mining district, in the central part of the Sanandaj-Sirjan zone. Gold mineralization occurs in ductile to ductile-brittle shear zones and is comparable with orogenic gold deposits. Silicification and sulfidization are the most important hydrothermal alteration features in the inner parts of altered shear zones and coincide most closely with the...
The study area is located in the southern part of Qorveh granitoid complex. Investigation of textural and mineral chemistry evidence in granitoid host with composition of granodiorite, granite, qtz-monzonite, and mafic microgranular enclave (MME) with composition of qtz-diorite to meladiorite, are focused in this paper. Microscopic study and data of microprobe analyses in host and enclave rocks...
