Vertically extensive and unstable magmatic systems: a unified view of igneous processes
BACKGROUND For more than 100 years, the melt-dominated magma chamber has been
central to conceptual models of volcanism and igneous processes. Over the past few …

Construction and evolution of igneous bodies: Towards an integrated perspective of crustal magmatism
Field, geochronological and geophysical studies show that many igneous bodies are
emplaced incrementally, growing by accretion of successive magma sheets. The existence …

A reactive porous flow control on mid-ocean ridge magmatic evolution
Mid-ocean ridge basalts (MORB) provide fundamental information about the composition
and melting processes in the Earth's upper mantle. To use MORB to further our …

Igneous layering in basaltic magma chambers
Layering is a common feature in mafic and ultramafic layered intrusions and generally
consists of a succession of layers characterized by contrasted mineral modes and/or mineral …

Cumulate formation and melt extraction from mush-dominated magma reservoirs: the melt flush process exemplified at mid-ocean ridges
Volcanism is the surface expression of extensive magmatic systems, with their intrusive
counterpart representing~ 80% of the total magma budget. Our knowledge of igneous …

Dynamics of evolving magma chambers: textural and chemical evolution of cumulates at the arrival of new liquidus phases
Basaltic magma chambers are best exemplified by layered intrusions–fossilized natural
laboratories that historically constrain most fundamental principles of igneous petrology …

Plutonic xenoliths from Martinique, Lesser Antilles: evidence for open system processes and reactive melt flow in island arc crust
Abstract The Lesser Antilles Volcanic Arc is remarkable for the abundance and variety of
erupted plutonic xenoliths. These samples provide a window into the deeper crust and …

Porosity evolution of mafic crystal mush during reactive flow
The emergence of the “mush paradigm” has raised several questions for conventional
models of magma storage and extraction: how are melts extracted to form eruptible liquid …
