Magma reservoirs play a key role in controlling numerous processes in planetary evolution,
including igneous differentiation and degassing, crustal construction, and volcanism. For …

We consider the current state of our understanding of the rheology of two-phase magmas,
that is suspensions of either bubbles or crystals in a viscous silicate melt. The discussion is …

Differentiation of mantle-derived, hydrous, basaltic magmas is a fundamental process to
produce evolved intermediate to SiO 2-rich magmas that form the bulk of the middle to …

This introductory article provides a synopsis of our current understanding of the form and
dynamics of magma reservoirs in the crust. This knowledge is based on a range of …

The structure of upper crustal magma plumbing systems controls the distribution of
volcanism and influences tectonic processes. However, delineating the structure and …

Abstract Olivier Bachmann is Professor of volcanology and magmatic petrology at the ETH
Zürich. He obtained his PhD at the University of Geneva, and held positions of post-doctoral …

We review our understanding of the exsolved volatile phase co-existing with magmas during
pre-eruptive storage at the pressures and temperatures corresponding to crustal magma …

When considering the rheology of a suspension the fundamental physical aspect to be
quantified is the redistribution of strain between the deformable matrix fraction of the …

Volcanic eruptions are common, with more than 50 volcanic eruptions in the United States
alone in the past 31 years. These eruptions can have devastating economic and social …

Partially molten rocks, often called a mush, are examples of a hydrogranular mixture where
the dynamics are controlled by both fluid and crystal‐crystal interactions. An obstacle to …
