This study documents the geology, mineralogy, geochronology and geochemistry of the
Sepon Mineral District (SMD) gold and copper deposits. The SMD is located in the Sepon …

Process models for ore formation in magmatic Ni–Cu–platinum group element (PGE) sulfide
systems require that S saturation is achieved in a mafic–ultramafic magma. Traditional …

Large bulk-tonnage high-sulfidation gold deposits, such as Yanacocha, Peru, are the
surface expression of structurally-controlled lode gold deposits, such as El Indio, Chile. Both …

The method of quasi-equilibrium directed crystallization was used for experimental modeling
of the behavior of Pt, Pd, and Au in the presence of As, Te, Bi, and Sn during the fractional …

The Kylm~ koski deposit consists of a disseminated primary Ni-Cu mineralization hosted by
a differentiated ultramafic body. It also shows sulfide veins (tens of meters long and up to 20 …

The association of large Au–Cu–Ag ore deposits with convergent margins is commonly
attributed to the higher content of chalcophile elements in the parental magmas generated at …

Porphyry Cu can contain significant concentrations of platinum-group elements (PGE: Os, Ir,
Ru, Rh, Pt, Pd). In this study, we provide a comprehensive in situ analysis of noble metals …

Assessment of geological, geochemical and isotopic data indicates that a significant
subgroup of volcanic-hosted massive sulphide (VHMS) deposits has a major or dominant …

Symplectites comprising clausthalite (PbSe) and host Cu-(Fe)-sulphides (chalcocite, bornite,
and chalcopyrite) are instructive for constraining the genesis of Cu-Au-(U) ores if adequately …

Essential resources of many rare metals including copper, zinc, molybdenum, silver and
gold occur in natural sulfide mineral deposits. Understanding the origin of these metal …
