The Muteh gold deposit (NE of Golpaygan) in the central part of intrusive-metamorphic belt of Sanandaj-Sirjan zone comprises NW-SE trending gold-quartz vein occurred in metamorphic complex. Gold mineralization is associated with quartz veins that formed during regional deformation across the mylonitic zones in metamorphic rocks of predominantly meta-volcanic, gneiss and schist. The sulfidation ...
A suite of Permian sylvite samples from Boulby potash mine, Yorkshire, UK, consistently yield traces of hydrogen upon analysis by a cold crush technique for liberating volatiles from entrapped fluid inclusions. In contrast, accompanying halite samples do not yield hydrogen. These data suggest the formation of hydrogen by radiolysis of water due to irradiation from potassium in the sylvite. The ...
A technique is described for the routine preparation of seminal fluid specimens for transmission electron microscopy. The method is applicable to cases where examination of sperm morphology is required and can also be used for the indentification of non-spermatozoal cells and their inclusions.
in this paper the substantiation of the method of full averaging for fuzzy differential inclusions is considered. these results generalize the results of [17, 20] for differential inclusions with hukuhara derivative and of [18] for fuzzy differential equations.
Mineralogy and fluid inclusion investigations in the Zarshuran gold deposit, north of Takab, NW Iran
The Zarshuran Carlin-type gold deposit is located about 30 km north of Takab, West-Azarbaidjan Province, NW Iran. Interaction between the ore-forming fluids and the host carbonates and shales resulted in development of the decarbonatization, argillic, alunite, silicic, and sulfide alteration zones in the study area. Based on mesoscopic and microscopic studies on drill core samples, gold mineral...
In a steel-refining ladle, the properties of manufactured steel can be notably degraded due to presence excessive inclusions. Stirring via gas injection through porous plug is often used as part process reduce these this paper, 3D computational fluid dynamics (CFD) modeling analyze transient multiphase flow and inclusion removal in gas-stirred ladle. The effects stirring with bubble-inclusion i...
Crystals of halite and sylvite within the Monahans (1998) H5 chondrite contain aqueous fluid inclusions. The fluids are dominantly sodium chloride-potassium chloride brines, but they also contain divalent cations such as iron, magnesium, or calcium. Two possible origins for the brines are indigenous fluids flowing within the asteroid and exogenous fluids delivered into the asteroid surface from...
Varicella zoster virus (VZV) pneumonitis and brainstem encephalitis developed in an immunocompetent adult without rash. Chest computed tomography exhibited nodularity; lung biopsy revealed multinucleated giant cells, Cowdry A inclusions, VZV antigen, and DNA. Varicella zoster virus central nervous system disease was verified by cerebrospinal fluid (CSF) anti-VZV IgG antibody with reduced serum/...
In this study, we performed high resolution 3D Raman mapping on primary multiphase fluid inclusions from a granulite and an eclogite of the Cabo Ortegal Complex (NW Spain), latter representing former subduction zone environment. Several microns-sized are great targets to test advantages limitations mapping. We show how optical scattering properties phases inside can affect veracity both 2D maps...
Introduction: Fluid inclusions are micron-scale volumes of fluid entrapped during the precipitation of minerals. Fluids are entrapped during primary mineral growth, and during healing of later fractures. The water in fluid inclusions in minerals precipitated in the upper crust of Mars contains a record of the ambient environment during precipitation. This includes data on fluid temperature and ...
