Pyritic shale horizons of the Newland Formation (Belt Series, Mid-Proterozoic) show striking similarities to Proterozoic pyritic shales elsewhere that are host to major lead-zinc deposits, such as Mt. Isa and McArthur River. However, in contrast to these deposits the pyritic shales of the Newland Formation contain only minute quantities of lead and zinc. Elevated concentrations of lead and zinc...
the iranian east magmatic assemblage (iema) in the central lut region, hosted porphyry and vein-type polymetallic mineralization. the galechah-shurab mining district is located in nw of the iema. volcanic and subvolcanic bodies in the area are composed of calc-alkaline porphyry quartz-latite, porphyry dacite and rhyodacite and hornblende-biotite andesite, equivalent to i-type granite. they empl...
The study area is located at northeast of Neyshabour in the Khorasan Razavi Province, northwest Arghash Gold Mine. The rocks of area are composed of polutonic to subvolcanic units with acid- intermediate in composition. They consist of granodiorite, diorite and granite. Alteration zones are: propylitic, sericitic, silicified and argillic. In the study area, mineralization is divided into two ty...
The Kangjiawan deposit, in the Shuikoushan district, Hunan Province, China, is a representative hydrothermal Pb–Zn–Ag– Au deposit in this region. The orebodies consist mainly of pyritic Pb–Zn ores. Silver minerals are associated with Pb–Zn mineralization. Ag-bearing Pb–Zn ores in the deposit are characterized by Ag > Cu > Sb content. Silver occurs mainly as silver minerals, such as minor argent...
The Miocene magmatic intrusion in the Tavşanlı zone of the Kütahya-Bolkardağ Belt (KBB) in the northwestern region of Turkey is represented by the Eğrigöz granitoids. This paper studies the petrology and geochemistry of hydrothermal alterations associated with the vein-type Cu-Pb-Zn mineralization hosted by this pluton, focusing on the determination of the mass gains and losses of chemical comp...
Natanz, 1:100000 geological map, is located in northeast Isfahan, in the Urumieh-Dokhtar structural zone. This sheet is a prospective area for Cu, Zn and Pb mineralization. Spatial distribution of geochemical anomalies for mineralization was identified; using pathfinder elements statistic method. The sample from catchment basin technique was applied on stream data. Then threshold elements were...
The Haft-Savaran Pb-Zn mineralization zone with the lower Jurassic age is located in the southern basin of Arak and Malayer-Isfahan metallogenic belt of Iran. Based upon the geological map of the Haft-Savaran area, the sandstone and shale of lower Jurassic are the main rocks of Pb-Zn deposit. In this area, 170samples were taken from 33 boreholes, and44 elements were measured by the ICP-MS metho...
Application of biosolid on land has been widespread in numerous countries for last several decades. This study performed incubation experiments by mixing a neutral loamy soil and biosolid enriched in Cu, Pb and Zn to explore how heavy metal affects soil mineralization and microbial biomass. The experimental results indicated that large nutrient, microorganism and C sources from biosolid were be...
For the purpose of this work an epiphytic lichen species, Hypogymnia physodes (L.)NyL, was used. Thalli of the lichen were treated with solutions of nitrate salts of heavy metals, including Zn(NO3)2, Cu(NO3)2, Pb(NO3)2, and Cd(NO3)2. To simulate the acid rain impact, pH of the metal mixture was lowered to pH 4, using Na2S2O5. Content of heavy metals was determined after a standard UV mineraliza...
Palk strait estuarine water was highly polluted by Cu, Fe, Pb, Zn and Hg. The study was carryout the interactions between heavy metals and microorganisms. The study area paying attention on the role of probiotic bacteria such as Bacillus cereus, Aeromonas hydrophila, Pseudomonas aeruginosa, Azotobacter vinelandii, and Lactobacillus sp. to remove the metals from polluted nine aquaculture ponds t...
