The emerging concept of a magma reservoir is one in which regions containing melt extend
from the source of magma generation to the surface. The reservoir may contain regions of …

Layered intrusions are fossilized natural laboratories that historically have constrained many
fundamental principles of igneous petrology. Layered intrusions are typically stratiform …

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 …

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 …

One of the outstanding problems in understanding the behavior of intermediate-to-silicic
magmatic systems is the mechanism (s) by which large volumes of crystal-poor rhyolite can …

Crystal mush is rapidly emerging as a new paradigm for the evolution of igneous systems.
Mid-ocean ridges provide a unique opportunity to study mush processes: geophysical data …

Volcanism is the surface expression of extensive magmatic systems, with their intrusive
counterpart representing~ 80% of the total magma budget. Our knowledge of igneous …

Crystal-melt separation is important for understanding the evolution of granitic magma and
the connection between plutonic and volcanic rocks. Crystal accumulation and melt …

Basaltic magma chambers are best exemplified by layered intrusions–fossilized natural
laboratories that historically constrain most fundamental principles of igneous petrology …

Before large volumes of crystal poor rhyolites are mobilized as melt, they are extracted
through the reduction of pore space within their corresponding crystal matrix (compaction) …
