The Ma’danjoo prospect area is one of the eastern anomalies of Khaf’s Sangan iron mine in southeast of Mashhad. Geological units in the area include Jurassic sedimentary rocks, skarn, and Tertiary subvolcanic intrusion with monzonitic composition. Skarns have been seprated  in to 7 zones on the basis of abundance and type of the calc-silicate including: garnet, pyroxene-garnet, pyroxene, phlogo...

The Upper Devonian - Lower Carboniferous Sourian complex, is composed of clastic - carbonates, volcanic, metamorphic rocks and quartz lenses hosts copper mineralization in Gian area of Fars province. This complex is metamorphosed to green schist facies. This metamorphism resulted In massIve to disseminated sulfide mineralization in the direction of schistosity and within quartz lenses. L...

Mineralization and associated fluid migration events in the c . 1500 km 2 North Pennine Orefield (NPO) are known to be with tectonic activity, but age of these origins base metal sulfide mineralization remain unresolved. New fieldwork Alston Block shows that post-dates a weakly developed phase north–south shortening consistent far-field Variscan basin inversion during late Carboniferous. observ...

Abstract The Herberton Mineral Field in Northeast Australia hosts world class magmatic-hydrothermal Sn–W polymetallic deposits that are enriched In. Baal Gammon and Isabel from the contains early tin, as cassiterite, overprinted by sulfide mineralization chalcopyrite, sphalerite, galena, pyrrhotite, stannite. We investigated distribution of In ores these two deposits, calculated temperature for...

Large constructed wetlands, known as stormwater treatment areas (STAs), have been deployed to remove phosphorus (P) in drainage waters before discharge into the Everglades in South Florida, USA. Their P removal performance depends on internal P cycling under typically hydrated, but with occasionally desiccated, conditions. We examined the spatial and temporal P removal capacity under different ...

Agh-Darreh copper deposit is located in Tarom area, about 25 km north of Abhar city. Main alterations identified in this region include silicic, argillic, and propylitic. Andesite and silica veins host sulfide mineralization. Chalcopyrite and pyrite are the main hypogene minerals accompanied by gold and silver in siliceous veins, with smaller amounts of galena. Malachite, azurite and goethite a...

A novel sulfate-reducing bacterium isolated from fuel-contaminated subsurface soil, strain PRTOL1, mineralizes toluene as the sole electron donor and carbon source under strictly anaerobic conditions. The mineralization of 80% of toluene carbon to CO2 was demonstrated in experiments with [ring-U-14C]toluene; 15% of toluene carbon was converted to biomass and nonvolatile metabolic by-products, p...

Experimental data and simulations were used to investigate the seasonal coupling between carbon, nitrogen and oxygen cycles in marine sediments from a eutrophic shallow lagoon in the Mediterranean Sea area. A negative seasonal correlation was observed between oxygen consumption and coupled nitrification–denitrification rates in surface sediments. Elevated values of oxygen consumption rates were...

Various methods can be used to evaluate in situ volumetric water content; however, when continuous measurements are required, only dielectric methods can be used. For equipment based on these methods, in the mining environment and particularly in environments having high sulfide contents (or acid-generating minerals), the accuracy of measurements can be affected by the chemistry of the solid an...

The study area is located about 45 km of southwest Neyshabour and east of Arghash village. Both intrusive and volcanic rocks are exposed in the study area and they are intensively altered due to hydrothermal fluid. The alteration zoning in the study area consists of potassic, sericitic, carbonatization, silicification and propylitic. More than 10 intrusive rocks with composition in the range of...
