Porphyry deposits are large, low-grade metal ore bodies that are formed from hydrothermal
fluids derived from an underlying magma reservoir. They are important as major sources of …

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 …

Continental China is a mosaic of numerous tectonic blocks, which amalgamated from
Neoarchean to Cenozoic broadly coeval with the cycles of global supercontinents such as …

Porphyry deposits supply most of the world's Cu and Mo resources. Over 90% of the
porphyry deposits are found at convergent margins, especially above active subduction …

Oxygen fugacity (fO 2) is a key factor that controls the formation of porphyry Cu deposits.
Porphyry Cu deposits are typically oxidized, but when and how porphyry magmas gain their …

Piston cylinder experiments are used to investigate the effect of oxygen fugacity (ƒO 2) on
sulphur speciation and phase relations in arc magmas at 0.5–1.5 GPa and 840–950° C. The …

Abstract The Kerman Cenozoic magmatic arc (KCMA), located on the southeast of the
Central Iranian volcano-plutonic belt, hosts some world class porphyry copper deposits …

Abstract The Late Mesozoic Qianlishan granitic complex in the western Nanling Range,
South China is associated with the Shizhuyuan giant W–Sn–Mo–Bi polymetallic deposit. It …

Heavy rare earth elements (HREE) are dominantly mined from the weathering crusts of
granites in South China. Although weathering processes occur globally, no economic HREE …

Pyrite is ubiquitous in the world-class iron oxide copper-gold (IOCG) deposits of the
Candelaria-Punta del Cobre district, documented from early to late stages of mineralization …
