Renewed economic interest in iron oxide–apatite (IOA) deposits—containing tens to
hundreds of millions of tonnes of Fe and substantial amounts of rare earth elements, P, Co …

The Searchlight pluton (SLP) and coeval Highland Range volcanic sequence (HRV) have
been suggested to represent intruded and erupted counterparts, and the 15 km tilted crustal …

We derive a novel method for determining the oxidation state of a magma as zircon
crystallized, with a standard error of±0· 6 log unit ƒO2, using ratios of Ce, U, and Ti in zircon …

Biotite (sensu lato) is a widespread rock‐forming mineral in magmatic rocks that can be
stable in a broad range of pressure and temperature, but appropriate biotite thermometers or …

Chemical diversity in convergent margin magmas is a product of igneous differentiation in
crustal hot zones, vertically extensive regions characterised by a low-volume (< 20%) mobile …

Oxygen fugacity (fO2) is a fundamental thermodynamic property governing redox potential in
solid Earth systems. Analysis of magmatic fO2 aids our understanding of the valence state …

Abstract The giant Pulang porphyry Cu-Au district (446.8 Mt at 0.52% Cu and 0.18 g/t Au) is
located in the Yidun arc, eastern Tibet. The district is hosted in an intrusive complex …

Abstract The Red Chris porphyry Cu-Au deposit is located in the Stikinia island-arc terrane
in northwest British Columbia. It is hosted by the Red Stock, which has five phases of …

Understanding the anatomy of magma plumbing systems of active volcanoes is essential not
only for unraveling magma dynamics and eruptive behaviors but also to define the …

Magmatic sources of porphyry deposits in postcollisional settings remain controversial. We
have used new and published petrological and geochemical data for the Eocene–Oligocene …
