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

The abundances of CO2, H2O, S and halogens dissolved in basaltic magmas are strongly
variable because their solubilities and ability to be fractionated in the vapor phase depend …

Caldera-forming volcanic eruptions are low-frequency, high-impact events capable of
discharging tens to thousands of cubic kilometres of magma explosively on timescales of …

Processes involved in the development of igneous and metamorphic rocks involve some
combination of crystal growth, solution, movement and deformation, which is expressed as …

Deep-sea submarine eruptions are the least known type of volcanic activity, due to the
difficulty of detecting, monitoring, and sampling them. Following an intense seismic crisis in …

The majority of basaltic magmas stall in the Earth's crust as a result of the rheological
evolution caused by crystallization during transport. However, the relationships between …

Olivine is the principal mineral of kimberlite magmas, and is the main contributor to the
ultramafic composition of kimberlite rocks. Olivine is partly or completely altered in common …

The olivine macrocrysts found in oceanites, picrites and magnesian basalts erupted at
hotspot volcanoes are generally interpreted either as phenocrysts crystallized from the …

Chondrule textures depend on the extent of melting of the chondrule precursor material
when cooling starts. If viable nuclei remain in the melt, crystallization begins immediately …

Inclusions of basaltic melt trapped inside of olivine phenocrysts during igneous
crystallization provide a rich, crystal-scale record of magmatic processes ranging from …
