Structural analysis of quartz vein systems and fluid inclusion criteria were used to distinguish five different fluid types which flowed through a segment of Palaeozoic crust in southwest England during the Variscan orogeny. Mineralogical constraints in combination with fluid inclusion thermobarometry enabled the temperature of vein formation to be estimated, and isotopic compositions of fluids...

National Specialty Society for Community Medicine Position Statement on Chrysotile Asbestos June 2010 Background The adverse health effects associated with exposure to asbestos exposure have been well established. Epidemiological, clinical, and laboratory studies have shown that asbestos is capable of causing lung cancer, mesothelioma, and a range of asbestos‐related diseases (International ...

Soursat Metamorphic Complex (SMC) in west of Takab city is one of the polyphase metamorphic terrenes in northern Sanandaj-Sirjan metamorphic belt of Iran. The SMC composed mainly of metasedimentary rocks associated with granitic intrusions. Based on metamorphic rocks, two metamorphic phases could be separate in the complex. M1 is representative of regional metamorphisms which varies from greens...

Hydrothermally altered samples from outcrops along the eastern Stillwater Range (NV), and scale and vein samples from Dixie Valley geothermal wells were collected for fluid-inclusion analyses. Fluidinclusion microthermometry and gas analysis by quadropole mass spectrometry were applied to establish the chemistry of the fluids trapped during alteration. Relationships between CO2/CH4, N2/Ar, and ...

The Kongsberg and Bamble lithotectonic domains of SE-Norway are known as classical Precambrian high-grade metamorphic terrains. area has undergone extensive metasomatism with formation albitites scapolite-rich rocks numbers previously economically important deposits including the Silver Modum Cobalt mines. We demonstrate here that central part domain (Kragerø area) locally developed low-grade m...

Abstract Gold mineralization in the El-Barramiya region of Eastern Desert, Egypt, is connected to post-accretionary stage throughout Central Desert. It represented by quartz, quartz-carbonate veins and disseminations listvenite rocks. The thrust contact between rock units area played an imperative part gold where obduction ophiolitic rocks over metasediments metavolcanics caused shear zones. Mi...

introduction the occurrence of blueschist metamorphic facies is believed to mark the existence of former subduction zones. this facies is represented in the main constituents of subduction-accretion complexes, where it occurs in separate tectonic sheets, imbricated slices, lenses, or exotic blocks within a serpentinite mélange (volkova et al., 2011). the evidence of the presence and maturity of...

Early Cambrian volcanic rocks of the Posht-e Badam tectonic block in Central Iran which is hydrothermally altered to green color rocks, hosts the Kiruna-type Iron Oxide-Apatite (IOA) mineralization in Anomaly 10 of Sechahun deposit. Geochemically, these volcanic rocks are classified as high-potassium calc-alkaline and mainly consist of rhyolite and trachyandesite. These rocks are important for ...
