Granite is one of the most important components of the continental crust on our Earth; it thus
has been an enduring studied subject in geology. According to present knowledge, granite …

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

Most magmatism on Earth forms by direct melting of the mantle, generating basalts at the
low silica end of the terrestrial compositional spectrum. However, most subduction zone …

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 …

The formation of crystal-poor high-silica rhyolite via extraction of interstitial melt from an
upper crustal mush predicts the complementary formation of large amounts of (typically …

The formation of world class porphyry copper deposits reflect magmatic processes that take
place in a deeper and much larger underlying magmatic system, which provides the source …

Magmatic evolution creates crystal cumulates. In the current paradigm for the genesis of
evolved magmas, cumulate crystal mushes dominate trans-crustal magma systems that feed …

U–Th–Pb zircon geochronology is an essential tool for quantifying the emplacement,
differentiation and thermal evolution of crustal magmatic systems. However, the power of U …

Abstract Among S-, I-, and A-type granites, the latter are the most debated in terms of origin,
and metasedimentary crust is usually discarded as a potential source. Here we tackle this …
