nakhlak lead mine is located at the nakhlak mountain 55 km ne of anarak town in isfahan province. the mineralogy is simple; galena and barite are the main primary minerals and cerussite is the main secondary mineral. sphalerite, pyrite, chalcopyrite, tetrahedrite-tennantite and acanthite occur as minor and trace mineral inclusions in galena. secondary minerals are anglesite, plattnerite, wulfen...

introduction the senj deposit has significant potential for different types of mineralization, particularly porphyry-like cu deposits, associated with subduction-related eocene–oligocene calc-alkaline porphyritic volcano-plutonic rocks. the study of fluid inclusions in hydrothermal ore deposits aims to identify and characterize the pressure, temperature, volume and fluid composition, (ptx) cond...

Abstract. Discovering ore deposits is becoming increasingly difficult, and this particularly true in areas of glaciated terrains. As a potential exploration tool for such terrains, we test the vectoring capacities trace element sulfur isotope characteristics pyrite, combined with quantitative statistical methods whole-rock geochemical datasets. Our target Rajapalot gold–cobalt project northern ...

Abstract Drill core samples from the Profitis Ilias Pb-Zn-Cu-Ag-Au vein mineralization on Milos Island, Greece provide new insights into (i) metal sources, (ii) primary vertical metal(loid) distribution, and (iii) supergene enrichment processes in a transitional shallow-marine to subaerial hydrothermal environment. Metal contents of unaltered altered host rocks combined with Pb isotope analyses...

The Kiruna mining district, Sweden, known for the type locality of Kiruna-type iron oxide–apatite (IOA) deposits, also hosts several Cu-mineralized deposits including oxide–copper–gold (IOCG), exhalative stratiform Cu-(Fe-Zn), and structurally controlled to stratabound Cu ± Au. However relationship between IOA Cu-systems has not been contextualized within regional tectonic evolution. A broader ...

The Salobo iron oxide copper-gold (IOCG) deposit host an important Cu-mineralization of the Carajás Mineral Province. ore is characterized by association (bornite-chalcocite-digenite) hosted magnetite and biotite-garnet schists. These rocks record distinct stages superimposed hydrothermal alteration dynamic metamorphism. Three different occurrences constitute bodies: a pristine to inclusion-poo...

To reveal the impact of irrigation management on the release and leaching of soil metals (Cu, Zn, Pb, Cr, and Cd), deep percolation rate and metals contents in soil solutions were observed in rice fields with nonflooding controlled irrigation (NFI) and flooding irrigation (FI) treatments. The contents of Cu and Cr in the deep solutions were safe according to the environmental quality standard f...

In Saccharomyces cerevisiae, at least 12 genes are important for cells to propagate in medium containing elevated concentrations of copper salts (J. Welch, S. Fogel, C. Buchman, and M. Karin, EMBO J. 8:255-260, 1989). Complementation studies were carried out on a copper-sensitive mutation (cup14) from this group. A new yeast gene, designated SLF1, was identified as a multicopy suppressor of the...

Soil samples in Moryayla village located 156 km northeast of Erzurum and Cu mineralization area around it were collected randomly. In these samples, 20 taken order to investigate the metals found pollution limits sources that cause this pollution. The geochemical analyzes (Cd, Cr, Cu, Ni, Pb, Zn Fe) soil made evaluated with parameters. calculation parameters, enrichment factor (EF); geoaccumula...
