This paper provides a review of the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER), Advanced Land Imager (ALI), and Hyperion data and applications of the data as a tool for ore minerals exploration, lithological and structural mapping. Spectral information extraction from ASTER, ALI, and Hyperion data has great ability to assist geologists in all disciplines to map the d...

With >90 known deposits containing original reserves of >2400 Mt sulfide ore, the Iberian Pyrite Belt (IPB) is largest volcanogenic massive (VMS) province on Earth. In these evolving mineral systems, texturally different pyrite exhibits characteristic mineralogy and trace element fingerprints. (Py-1), which well preserved in polymetallic ores that crystallized at earliest stage VMS deposit form...

The anionic and cationic species of elements from deeply buried deposits migrate to the near surface driven by various geological forces. applied electric field is used collect these active ions designed electrode, with a negative charge go anode positive cathode, which called electrogeochemical exploration method, also CHIM. Prospecting effect has been investigated researchers since coming up ...

estimation of gold reserves and resources has been of interest to mining engineers and geologists for ages. the existence of outlier values shows the economic part of the deposits subject to the fact that don’t depend on the human or technical errors. the presence of these high values causes a pseudo dramatically increment in variance estimation of economical blocks when applying conventional m...

the muteh gold deposit (ne of golpaygan) in the central part of intrusive-metamorphic belt of sanandaj-sirjan zone comprises nw-se trending gold-quartz vein occurred in metamorphic complex. gold mineralization is associated with quartz veins that formed during regional deformation across the mylonitic zones in metamorphic rocks of predominantly meta-volcanic, gneiss and schist. the sulfidation ...

Academic insignia of the Faculty Chemical Technology UCT Prague have a history and are used in academic ceremonies (graduation, ceremonial scientific councils, awarding honorary doctorates, etc.). Insignia consists single chain with medal scepter. They made gold-plated silver decorated natural synthetic precious stones. The central motif head sceptre is pentagonal dodecahedron cut from sulphide...

Abstract As a result of the analysis data available and collected in recent years, contrast to well-established ideas about polygenic poly-stage nature mineralization, it is indicated that gold mineralization Central Kyzyl Kum formed as formation single ore-magmatic system, which develops same type regardless composition age host rocks; during deposits, most important thing presence process pro...

Generalization of the results study placer gold and mechanisms its distribution in east Siberian Platform made it possible for first time to reveal that ore sources gold-bearing placers were mainly mineralization gold-sulfide formation formed under influence hydrothermal metasomatic processes occurred deep fault zones. It is determined hydrothermal-metasomatic formations rock are amagmatic, nea...

the massive sulphide deposit at kantienpan cu-zn mine is hosted by volcano sedimentary succession known as the areachap group, in the eastern part of namaqua metamorphic province, south africa. the deposits were affected by a complex deformation and metamorphic history and represent examples of upper amphibolite to granulite grade metamorphosed volcanic-hosted massive sulphide (vhms) depo...
