Melt extraction from the partially molten mantle is among the fundamental processes
shaping the solid Earth today and over geological time. A diversity of properties and …

The thermal structure of subduction zones is fundamental to our understanding of the
physical and chemical processes that occur at active convergent plate margins. These …

Arc magmas globally are H2O-Cl-S–rich and moderately oxidized (ΔFMQ=+ 1 to+ 2) relative
to most other mantle-derived magmas (ΔFMQ≤ 0). Their relatively high oxidation state limits …

A first-order observation of convergent margin volcanism is that continental arc
stratovolcanoes have substantially elevated incompatible element abundances and notable …

The Famatinian arc, over central-western Argentina, is one of the few examples of exposed
crustal arc cross-section in the world. This Paleozoic magmatic arc and orogenic system on …

Porphyry Cu deposits form in the shallow crustal parts of arc magmatic systems, which root
in the mantle wedge, evolve in lower crustal MASH (melting, assimilation, storage …

Multiphase reactive transport processes are ubiquitous in igneous systems. A challenging
aspect of modelling igneous phenomena is that they range from solid-dominated porous to …

Decades of study on volcanic arcs have provided insight into the overarching processes that
control magmatism, and how these processes manifest at individual volcanoes. However …

During the differentiation of arc magmas, fractionating liquids follow a series of cotectics,
where the co‐crystallization of multiple minerals control the melt compositional trajectories …

We develop a 3‐D isotropic shear velocity model for the Alaska subduction zone using data
from seafloor and land‐based seismographs to investigate along‐strike variations in …
