Over the past 25 years, our understanding of the physical processes that drive volcanic
eruptions has increased enormously thanks to major advances in computational and …

The magmatic-hydrothermal evolution of the El Teniente porphyry Cu-Mo deposit in the
Central Andes in Chile is reconstructed based on field relationships, scanning electron …

Porphyry systems supply most copper and significant gold to our economy. Recent studies
indicate that they are frequently associated with high Sr/Y magmatic rocks, but the meaning …

In this study potential iron isotope fractionation by magmatic processes in the Earth's crust
was systematically investigated. High precision iron isotope analyses by MC-ICP-MS were …

Gas loss from ascending magma controls the chemical and physical evolution of volcanic
systems. Melt inclusions trapped in volcanic phenocrysts contain snapshots of volatile …

Crystals in hydrous magmas can form in response to falling temperature (magma cooling) or
degassing (magma decompression). It remains unclear which process dominates beneath …

We have measured the Li isotope ratios of a range of co-existing phases from peridotites
and mafic magmas to investigate high-temperature fractionations of 7Li/6Li. The Li isotopic …

The textures of minerals in volcanic and plutonic rocks testify to a complexity of processes in
their formation that is at odds with simple geochemical models of igneous differentiation …

The fluid-melt partition coefficients of ten trace metals (Li, Mn, Cu, Zn, Rb, Sr, Mo, W, and Pb,
along with K) between hydrous evolved melts and coexisting Cl-bearing fluid (s) have been …

Vulcanian eruptions are common at many volcanoes around the world. Vulcanian activity
occurs as either isolated sequences of eruptions or as precursors to sustained explosive …
