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

Volcanic eruptions can represent major societal hazards. Placing tighter bounds on the
timescales of magmatic processes that precede eruptions is, therefore, important for volcano …

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 …

Large caldera-forming eruptions have long been a focus of both petrological and
volcanological studies; petrologists have used the eruptive products to probe conditions of …

The most voluminous silicic volcanic eruptions in the geological past were associated with
caldera collapses above giant silicic magma reservoirs. The thermal evolution of these sub …

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 …

Silicic magmas play an important role in the formation of continental crust and are
responsible for some of the most hazardous volcanic eruptions on the planet. Low-δ 18 O …

Magma dominantly exists in a slowly cooling crystal-rich or mushy state,,. Yet, observations
of complexly zoned crystals, some formed in just one to ten years,,,,, as well as time …

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 …

Supereruptions are the largest explosive volcanic eruptions on Earth. They generate
catastrophic, widespread ash-fall blankets and voluminous ignimbrites, with accompanying …
