In situ 4D experiments at high temperature and moderate pressure reveal that rapid dendritic crystallization in hydrous basaltic magmas promotes a rheological transition within minutes, controlling magma mobility within the Earth’s crust.

The mobility of basaltic magma within the Earth’s crust is controlled by magma viscosity. Crystallization and crystal morphology affect the viscosity, mobility and ultimately eruptibility of magma, by locking it at depth or enabling its ascent towa

Basaltic volcanoes exhibit a wide range of eruptive styles, from relatively gentle effusive eruptions (producing lava flows and lava domes) to highly explosive activity (where pyroclastic materials are ejected from the vent as a jet or plume). The di

This study shows how a few nanometer-sized crystals markedly increase the viscosity of a magma leading to explosive eruptions.
Although gas exsolution is a major driving force behind explosive volcanic eruptions, viscosity is critical in control

Quantifying the oxidation state of multivalent elements in silicate melts (e.g., Fe2+ versus Fe3+ or S2- versus S6+) is fundamental for constraining oxygen fugacity. Oxygen fugacity is a key thermodynamic parameter in understanding melt chemical hist

Basaltic eruptions are the most common form of volcanism on Earth and planetary bodies. The low viscosity of basaltic magmas generally favours effusive and mildly explosive volcanic activity. Highly explosive basaltic eruptions occur less frequently

The major and minor element chemistry of silicate glass is commonly measured using electron probe micro-analysis (EPMA). The volatile content (H2O ± CO2) can, additionally, be quantified using “volatiles by difference” (VBD), but a review of lit

Basaltic eruptions are the most common form of volcanism on Earth and planetary bodies. The low viscosity of basaltic magmas inhibits fragmentation, which favours effusive and lava-fountaining activity, yet highly explosive, hazardous basaltic erupti
