Magma Transport, Emplacement, and Eruption: A Petro-Rheological Perspective
Co-organized as NP9.12, co-sponsored by AGU-VGP
Convener: Mattia Pistone | Co-conveners: Hélène Balcone-Boissard, Mike Cassidy, Danilo Di Genova, Chiara P Montagna

Magmas forge the Earth's lithosphere, modulate its atmosphere and hydrosphere, and drive major biogeochemical changes through volcanism. Magmatic processes operating between crystals, melt, and gas bubbles at the smallest scales give rise to planetary-scale effects. The great challenge in understanding the dynamics of magmatism is the quantitative description of the numerous and interrelated thermo-chemical processes, integrating the dynamics operating on the micro-scales of single mineral, melt, and gas phases with the macro-scales of transport and deformation mechanics that allow magmas to migrate kilometers through the crustal realm.
We wish to stimulate cross-disciplinary collaboration among geologists, geochemists, petrologists, volcanologists, and rock physicists to probe the link between small- versus large-scale, slow versus fast magmatic and volcanic processes in order to reveal the mechanics of transport, emplacement, and eruption of multiphase magmas. We invite contributions from experimental, analytical, numerical, and field-based approaches. This session aims at bringing together the plethora of forensic disciplines in Earth Sciences to understand how we:
- investigate magma rheology and determine the volume and architecture of plutons and plumbing systems
- quantify time-integrated chemical, mechanical, and thermal processes driving magma flow and eruption
- determine the frequency and timescales of magma injections, dykes, and melt extraction events
- interrogate minerals, glasses and melts, or volatile emissions, to constrain microphysics of magmas
- decipher signs of volcanic unrest with respect to magmatic processes
- link volcanic and plutonic processes
at all spatial and temporal scales.
