The Pellapahk Cu-Mo and Oleninskoe Au-Ag deposits in the western segment of Russian Arctic Kolmozero–Voronya greenstone belt are considered two parts an Archean (2.83–2.82 Ga) porphyry-epithermal system, probably oldest one defined Fennoscandian Shield. Formation deposit at epithermal stage system is indicated by spatial genetic relationships with sills granite porphyry, geochemical association...

Quartz, carbonates and other minerals as e.g., realgar are present in veins caverns sedimentary rocks the Western Carpathians. In Polish segment, they have been characterized from mineralogical, petrologic, geochemical points of view, well fluid inclusions. Their characters discussed perspective a description particular types chaotic complexes—the tectonic mélange zones, distinguished Carpathia...

roudgaz prospect area is a cu, sn, pb, zn, and au polymetal vein system located to the southeast of gonabad and in the northeast of lut block. oxidan subvolcanic tertiary rocks with monzonite to monzodiorite porphyry composition intruded the metamorphic rocks of middle jurassic. the majority of intrusive bodies are affected by carbonation, argillic, sericitic, and silicification-tourmaline alte...

The 7XXX series alloys are heat-treatable Al-Zn-Mg or Al-Zn-Mg-Cu alloys. They develop their strength by solution heat treatment followed by ageing. In contrast to the 5XXX series alloys, the 7XXX series alloys do not respond favourably to cold work, because they are strengthened almost exclusively by GP zone formation and precipitates which nucleate from the GP zones. Introducing many new disl...

Magneto-optical imaging and magnetization measurements were applied to investigate local formation of superconducting phase effected by a random neck synthesis in Y-Ba-Cu-O system. Polished pellets of strongly inhomogeneous ceramic samples show clearly the appearance of superconducting material in the intergrain zones of binary primary particles reacted under different conditions. Susceptibilit...

The amount of glomalin-related soil protein (GRSP), a glycoprotein produced by arbuscular mycorrhizal fungi (AMF), its contribution to the sequestering of Cu and Zn in the soil, and the microsite variation of other soil traits (pH, water-stable aggregates--[WSA], soil organic carbon--[SOC]) was studied in a semi-arid Mediterranean ecosystem near a copper smelter and affected by deposit of metal...

The Sonju Lake intrusion (SLI) is a 1200-m thick, sheet-like, tholeiitic layered intrusion located within the 1096 Ma Beaver Bay Complex of NE Minnesota. Its cumulus stratigraphy of Ol Pl+Ol Pl+Cpx+Ol Pl+Cpx+Ox±Ol Pl+Cpx+Ox+Ol+Ap indicates formation by closed-system fractional crystallization of a tholeiitic magma. In 1999, outcrop sampling revealed a stratiform PGE-enriched interval within oxi...

The objective of the study was the analysis of trace elements contents in coals of the Upper Silesian Coal Basin (USCB), which may pose a potential threat to the environment when emitted from coal processing systems. Productive carbon overburden in central and southern zones of the USCB is composed mostly of insulating tertiary formations of a thickness from a few m to 1,100 m, and is represent...

Tarikdarreh prospect area is situated in northeastern Iran at the boundary between Central Iran and Kopet-Dagh structural zones. Torbat-e-Jam granitoid intrusion of Triassic age is the main magmatic display in the district. These plutonic rocks with NW-SE trending intruded Miankouhi Formation (Upper Triassic) consisting of coaly shale, siltstone and sandstone converting those to hornfels for te...
