Global data for measured Fe 2 O 3/FeO ratios and Cu contents in unaltered volcanic and
intrusive arc rocks indicate that, on average, they are slightly more oxidized than other …

▪ Abstract The Re-Os isotope sytem, based on the long-lived β− transition of 187Re to
187Os, has matured to wide use in cosmochemistry and high-temperature geochemistry …

Ore deposits are loci on Earth where energy and mass flux are greatly enhanced and
focussed, acting as magnifying lenses into metal transport, fractionation and concentration …

Porphyry deposits arguably represent the most economically important class of nonferrous
metallic mineral resources. These magmatic-hydrothermal deposits are characterized by …

Cobalt is in high demand because of the key role that cobalt-lithium-ion batteries are playing
in addressing the issue of global warming, particularly in facilitating the transition from the …

Nickel-copper sulfide deposits are found at the base of mafic and ultramafic bodies. All their
host rocks, except the Sudbury Igneous Complex, are thought to be mantle-derived melts …

We investigated the spatial-temporal distribution and the major, trace, and rare earth
element geochemistry, U-Pb zircon geochronology, and isotope geochemistry of mafic dike …

Accurate estimates of the sulfur content in silicate melts at sulfide saturation are required to
explain magmatic processes such as the origin and budget of sulfur in some volcanic …

The importance of externally derived sulfur in the genesis of sulfide-rich, magmatic Ni-Cu-
(platinum group element [PGE]) deposits remains a key, yet unresolved, issue. Calculations …

It has been suggested that a decrease in atmospheric methane levels triggered the
progressive rise of atmospheric oxygen, the so-called Great Oxidation Event, about 2.4 Gyr …
