In hyperalkaline () fluids that have participated in low-temperature (<150) serpentinization reactions, the dominant form of C is often methane (), but origin this uncertain. To assess serpentinite aquifers within Samail Ophiolite, Oman, we determined fluid chemical compositions, analyzed taxonomic profiles fluid-hosted microbial communities, and measured isotopic compositions hydrocarbon gases...
Endemic PCs and high incidence of malignant mesothelioma from household use of asbestos have been reported in Metsovo in northwestern Greece ("Metsovo lung"). In the present study, we present similar findings in six more areas of Greece. Like Metsovo, all these areas are located within ophiolite belts. Like Metsovo, material similar to "Metsovo whitewash" has been used for various domestic uses...
Indian J Med Sci, Vol. 62, No. 7, July 2008 In order to investigate the professionals adherence to measures o f s tandard precautions, we conducted a study at the 550-bed Imam Reza Teaching Hospital, Kermanshah, in September 2007. A total of 120 health care workers (nurses and paramedical staff) from different departments were surveyed using a standardized questionnaire. Data were analyzed usi...
According to the olivine and spinel chemistry, two types of peridotite were identified from west north Piranshahr ophiolite. Peridotite rocks are classified based on chemistry of spinel and olivine. Average number of Cr in spinels (Cr#[(100*Cr/(Cr+Al))]) and Mg-number (Mg#[100*Mg/(Mg+Fe)]) in dunite are 0.63 and 0.51 respectively. In harzburgite, Cr# is 0.33 and Mg# is 0.67 and in spinel from s...
Amphibolites are one of the major rock units in the Posht-e-Badam ophiolite that are formed by metamorphism of basalts. There are tow types of amphibolite in the Posht -e- Badam ophiolite: 1) amphibolites with intermediate plagioclase (first type), amphibole, plagioclase, quartz, sphene, ilmenite, apatite, sericite and epidote, 2) amphibolites with high content of anorthite (second type), amphi...
The Southern Caspian Sea ophiolite complex (SCO) is one of the Late Cretaceous discontinuous oceanic lithosphere remnants in northern Iran. These complex is almost a complete sequence from bottom to top, ultramafic cumulates, layered gabbros, isotropic gabbros, dike complex and basaltic lavas which is covered by Late Cretaceous (Companion- maaestirchtian) pelagic limestone. Crustal ultramafic c...
Fossil worm tubes of Cretaceous age preserved in the Bayda massive sulfide deposit of the Samail ophiolite, Oman, are apparently the first documented examples of fossils embedded in massive sulfide deposits from the geologic record. The geologic setting of the Bayda deposit and the distinctive mineralogic and textural features of the fossiliferous samples suggest that the Bayda sulfide deposit ...
Background: The motivational reasons for choosing dental specialties are highly variable among students. A deep understanding of these motives can greatly help in strategic planning this respect. Objectives: Thus, study aimed to explore the Methods: This qualitative evaluated viewpoints 17 students at School Dentistry, Kermanshah University Medical Sciences, Kermanshah, Iran who were selected v...
Ophiolites are widely studied to unravel how new subduction zones form. They may contain crustal and mantle rocks that formed during juvenile stages of intra-oceanic subduction, modifying the pre-existing oceanic lithosphere within which started, in a magmatic arc upon maturation. Previous geochemical work on Cretaceous Andaman Ophiolite its metamorphic sole, located forearc Sunda zone south-ea...
