A study of the platinum group element (PGE) distribution in various lowermost Cambrian rock types of the Kunyang phosphate deposit in south China revealed unusually high PGE concentrations (434 ppb Pt, 142 ppb Pd, 57.97 ppb Rh,

The location of magmatic Ni-Cu-PGE sulfide deposits is related to lithospheric architecture, particularly that of the subcontinental lithospheric mantle (SCLM). At crustal levels, this relationship is manifest by a close proximity to craton and [...]

Platinum-group elements (PGE) are typically hosted in base metal sulfides and by platinum-group minerals (PGM) in Ni-Cu-PGE sulfide deposits. At Sudbury, it appears that the majority of PGE are hosted in PGM. In order to understand why this is t[...]

Metal introduction at the late Paleocene to early Eocene Quellaveco porphyry copper-molybdenum deposit in southern Peru spans several phases of quartz monzonite porphyry emplacement and is bracketed by a precursor granodiorite pluton and a late-[...]

Pyrrhotite is commonly used to estimate the fugacity of sulfur in natural and experimental systems; however, in some instances, high-temperature pyrrhotites can incorporate copper to such an extent as to raise questions concerning the accuracy o[...]
