Molecular dynamics calculations suggest that molten hydrogen-bearing iron peroxide (FeO2Hx) may produce the ultra-low velocity zones that occur at the core-mantle boundary.
This former West Point graduate and coffee grower transformed igneous petrology and volcanology.
A synthesis of data from studies in different ocean basins reveals that the characteristics of oceanic crust are shaped by age and spreading rate.
A planned project will drill into a magma reservoir in Iceland that has never erupted to the surface, giving scientists a fresh look at Earth’s underground “plumbing.”
Hydrous silica-rich magmas can degas through connected bubble pathways when as little as 20% crystals are present, influencing transitions from explosive, Vulcanian-style eruptions to lava effusion.
There is a possibility of ancient volcanism on metallic asteroids, a new type of volcanism that is not yet observed, though the Psyche mission to the asteroid Psyche may change that soon.
A new study suggests alternative explanations for Io’s unusual magnetic field.
Seismometers near Iceland’s Bárðarbunga volcanic system pinpointed thousands of earthquakes in 2014–2015, revealing where molten rock was moving underground before any eruptions occurred.
Evidence from volcanic crystals sheds light on magma storage under Mount Agung and helps explain this giant volcano’s frequent eruptions.
A new study sheds light on how magma erodes the conduit it flows through.
