Shear Velocity Evidence of Upper Crustal Magma Storage Beneath Valles Caldera
Geophysical Research Letters, 2023 Valles Caldera was formed by large rhyolitic eruptions at ∼1.6 and 1.23 Ma and it hosts post‐caldera rhyolitic deposits as young as ∼69 ka, but the contemporary state of the magmatic system is unclear.

Rifting‐Driven Magmatism Along the Dead Sea Continental Transform Fault
Geophysical Research Letters, 2023 The Dead Sea Fault (DSF) is a crustal‐scale continental transform fault separating the African and the Arabian plates. Neogene to Quaternary volcanic activity is well‐spread in Northern Israel.

Magma flow through elastic-walled dikes [PDF]
, 2005 A convection–diffusion model for the averaged flow of a viscous, incompressible magma through an elastic medium is considered. The magma flows through a dike from a magma reservoir to the Earth’s surface; only changes in dike width and velocity over ...

Proceedings of the National Academy of Sciences, 2016 For those who remember the classic disaster-docudrama Supervolcano (BBC-Discovery Channel 2005), the adjective “eruptible” is likely to ring a bell. Set in the near future and generally quite scientifically literate, the movie envisions volcanologists trying desperately to evaluate the near-term threat posed by the giant Yellowstone magmatic system.

Halogen Enrichment of Siberian Traps Magmas During Interaction With Evaporites
Frontiers in Earth Science, 2021 Volatile emissions to the atmosphere associated with the Siberian Traps eruptions at the Permian-Triassic boundary were sourced from the outgassing of primary magmas and the sedimentary host rocks into which they were intruded. Halogens in volcanic gases

Redox state of Earth’s magma ocean and its Venus-like early atmosphere
Science Advances, 2020 Oxidation state of iron in Earth’s magma ocean indicates it would have produced a Venus-like early atmosphere upon cooling. Exchange between a magma ocean and vapor produced Earth’s earliest atmosphere. Its speciation depends on the oxygen fugacity (fO2)

Geochemistry, Geophysics, Geosystems, 2021 Thallium (Tl) isotope ratios are an emerging tool that can be used to trace crustal recycling processes in arc lavas and ocean island basalts (OIBs). Thallium is a highly volatile metal that is enriched in volcanic fumaroles, but it is unknown whether ...

Onset of solid-state mantle convection and mixing during magma ocean solidification [PDF]
, 2016 ©2017. American Geophysical UnionThe energy sources involved in the early stages of the formation of terrestrial bodies can induce partial or even complete melting of the mantle, leading to the emergence of magma oceans. The fractional crystallization of
