Field, geochronological and geophysical studies show that many igneous bodies are
emplaced incrementally, growing by accretion of successive magma sheets. The existence …

Polygenetic volcanoes and calderas produce eruptions of a wide variety of magnitudes,
chemistries, and recurrence times. Understanding the interplay between long-and short-term …

A thermodynamic model for estimating the saturation conditions of H 2 O–CO 2 mixed fluids
in multicomponent silicate liquids is described. The model extends the capabilities of rhyolite …

The thermodynamic modeling software MELTS is a powerful tool for investigating
crystallization and melting in natural magmatic systems. Rhyolite‐MELTS is a recalibration …

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 …

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

Granitic magmas extracted from crustal sources can form over a wide variety of P, T and aH
2 O conditions. Both fluid-present and effectively fluid-absent conditions can yield granitic …

A silicic ignimbrite flare-up episode occurred in the Pannonian Basin during the Miocene,
coeval with the syn-extensional period in the region. It produced important correlation …

The magmatic systems that give rise to voluminous crystal-poor rhyolite magma bodies can
be considered to operate on two contrasting timescales: Those governed by longer-term …

We present two-feldspar thermometry and diffusion chronometry from sanidine,
orthopyroxene and quartz from multiple samples of the Bishop Tuff, California, to constrain …
