The Sungun porphyry copper deposit is located in northwestern Iran and is associated with diorite/granodiorite to quartz-monzonite of Miocene age, which intruded Eocene volcanosedimentary and Cretaceous carbonate rocks. Copper mineralization was accompanied by both potassic and phyllic alteration. Three main mineralization related alteration episodes (potassic, transition, and phyllic alteratio...

Binary oxide semiconductors TiO2-ZrO2 and Cu-decorated TiO2-ZrO2 (TiO2-ZrO2-Cu) uniform films were sputtered on polyester (PES). These films were irradiated under low intensity solar simulated light and led to bacterial inactivation in aerobic and anaerobic media as evaluated by CFU-plate counting. But bacterial mineralization was only induced by TiO2-ZrO2-Cu in aerobic media. The highly oxidat...

NPS SYNTHESIS, CHARACTERIZATION AND AZO-DYE DEGRADATION A facile cost effective wet chemical method of synthesis is proposed for Cu-NPs, CuO-NPs and Cu-doped ZnO-NPs. The nanomaterials are opto-physically characterized for nano standard quality. Cu-doped ZnO-NPs based catalytic system is found to possess most efficient photocatalytic activity in degradation of two organic azo-dyes namely methyl...

introduction the study area is located in central part of the khaf- kashmar-bardeskan belt which is volcano-plutonic belt at the north of the dorouneh fault in the north of lut block. the north of the lut block is affected by tectonic rotation and subduction processes which occur in the east of iran (tirrul et al., 1983). the magmatism of lut block begins in jurassic and continues in tertiary (...

Copper sulfate is often added to broiler and laying hen diets at prophylactic dosages due to its antimicrobial and growth promoting effects despite reduced P digestibility, whereas P use from other Cu sources is unknown. Therefore, male broiler chicks were fed diets containing 0 or 250 ppm Cu from Cu sulfate (Cu SUL), Cu citrate (Cu CIT), Cu lysinate (Cu LYS), or CuCl from 9 to 22 d of age (8 c...

Four distinct types of fluid inclusion are associated with brecciation, alteration and mineralization in the Ilkwang Cu–W breccia-pipe deposit in the southeastern Kyongsang Basin, South Korea. The earliest fluid inclusions in igneous quartz have salinities of 35–49 wt% NaCl equiv. and homogenize by halite dissolution. This fluid exsolved directly from the melt. A CO2-bearing fluid (2–4 wt% NaCl...

A systematic comparison of Cu toxicity thresholds was made between freshly spiked soils and soils in which elevated Cu concentrations have been present for various times. Three uncontaminated soils were spiked and experimentally leached or incubated outdoors for up to 18 months. Additionally, five field-contaminated soils with a 6- to 80-year-old Cu contamination were sampled, and corresponding...
