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 …

Metals such as Cu, Mo, Au, Sn, and W in porphyry and related epithermal mineral deposits
are derived predominantly from the associated magmas, via magmatic–hydrothermal fluids …

The transport of water from subducting crust into the mantle is mainly dictated by the stability
of hydrous minerals in subduction zones. The thermal structure of subduction zones is a key …

The last 15yr have seen an explosion of data on the volatile contents of magmas parental to
arc volcanoes. This has occurred due to the intense study of melt inclusions trapped in …

Based on a compilation of published sources, rocks referred to as adakites show the
following geochemical and isotopic characteristics: SiO2≥ 56 wt percent, Al2O3≥ 15 wt …

Vanguard efforts in forecasting volcanic eruptions are turning to physics-based models,
which require quantitative estimates of magma conditions during pre-eruptive storage …

Partial melting at continental lithosphere depths plays an important role in generating
geochemical variations in igneous rocks. In particular, dehydration melting of ultrahigh …

Arc magma acquires continental crust-like trace element signatures through selective
recycling of incompatible elements from the subducted slab. The long-standing model of …

Phase and melting relations in deeply subducted sediments, the main reservoir of large ion
lithophile elements (LILE) in subduction zones, are of first order importance to understand …

The phase and melting relations in subducted pelites have been investigated experimentally
at conditions relevant for slabs at sub-arc depths (T= 600–1050° C, P= 2· 5–4· 5 GPa). The …
