Arc-basaltic melts of typical hydration state (≥ 2 wt% H 2 O) are buoyant relative to all
common crustal igneous rock types and may pass adiabatically from a mantle source …

Open-vent, persistently degassing volcanoes—such as Stromboli and Etna (Italy), Villarrica
(Chile), Bagana and Manam (Papua New Guinea), Fuego and Pacaya (Guatemala) …

Formation of hydrothermal mineralization is related to the late stages of, or immediate
following, orogenic compressional regimes that have been superimposed on arc …

Magmatic volatiles (for example, water) are abundant in arc melts and exert fundamental
controls on magma evolution, eruption dynamics and the formation of economic ore …

The transition to a low-carbon economy will increase demand for a wide range of metals,
notably copper, which is used extensively in power generation and in electric vehicles …

Porphyry Cu deposits are formed by Cu-and volatile (eg, Cl, S)-rich fluids exsolved from
underlying magma reservoirs. Intuitively, higher magmatic Cl and S contents likely …

In order to better constrain the partitioning behavior of Mo during the crystallization of upper
crustal granitic magmas, partition coefficients of Mo between aqueous fluids and granitic …

Adakites are Y-and Yb-depleted, SiO2-and Sr-enriched rocks with elevated Sr/Y and La/Yb
ratios originally thought to represent partial melts of subducted metabasalt, based on their …

Sulfide-rich hydrous arc cumulates in the lower crust are considered a likely source for
porphyry Cu-forming magmas in post-subduction settings. However, it remains controversial …

To meet surging requirements of copper for the green energy revolution, minable resources
subequal to all copper production in history must be found in the next two decades. We …
