The Kapuskasing Structural Zone transects the Wawa and Abitibi greenstone belts in Superior province of Canadian Shield. At southern margin (KSZ), Borden Gold deposit hosts low-grade-gold mineralization within upper amphibolite- to granulite-facies sillimanite-garnet-biotite gneisses. Here, we present geochemistry Lu-Hf geochronological studies a gold-hosting garnet-bearing gneiss constrain for...

The presented studies are aimed to determine the formation patterns of gold-rare metal mineralization within one most inaccessible Arctic islands Russian Federation, Bolshevik Island Severnaya Zemlya archipela-go. relevance work is determined by high probability discovering a significant in terms reserves deposit, which proved many researchers on example known large deposits be typical feature ...

This review paper aims to integrate geological, tectonic and metallogenetic data, including new propose a regional model for the gold (and base metal) mineralization in south Amazonian Craton support mineral exploration concerning magmatic–hydrothermal deposits. The Proterozoic evolution of comprises accretion terrains Archean Carajás Mineral Province. In Tapajós Juruena provinces, located at p...

Key constraints related to the nature of alteration and mineralization in geologically complex economically important iron oxide copper–gold (IOCG) systems remain highly speculative, especially, physicochemical characteristics hydrothermal fluids. This study was conducted on samples from Khetri Copper Belt (KCB) western India that hosts several IOCG-type deposits. The aims constrain qualitative...

The Tethyan Himalaya is the fourth metallogenic belt discovered to date within Tibetan Plateau and contains chromite, gold Sb–polymetallic mineralization. records a series of complex tectonic–magmatic events that include break-up, subduction, collision, detachment, obduction Eastern Gondwana continent, all which generated ideal conditions for ore formation. However, this area remains under-expl...

This article investigates the effect of material size on efficiency flotation concentration gold-copperarsenic ores Taror deposit (Republic Tajikistan) and studies dependence gold recovery duration process with purpose developing an alternative technological scheme for processing this ore type. According to X-ray phase analysis, samples consist rock-forming minerals by 92%. Ore mineralization i...
