Vapor-bubble growth in olivine-hosted melt inclusions
Melt inclusions record the depth of magmatic processes, magma degassing paths, and
volatile budgets of magmas. Extracting this information is a major challenge. It requires …

Deep long period volcanic earthquakes generated by degassing of volatile-rich basaltic magmas
Deep long-period (DLP) earthquakes observed beneath active volcanoes are sometimes
considered as precursors to eruptions. Their origin remains, however, unclear. Here, we …

[HTML][HTML] High CO2 in the mantle source of ocean island basanites
Some of the most CO 2-rich magmas on Earth are erupted by intraplate ocean island
volcanoes. Here, we characterise olivine-hosted melt inclusions from recent (< 10 ky) …

Diffusive equilibration of H2O and oxygen fugacity in natural olivine-hosted melt inclusions
J Humphreys, M Brounce, K Walowski - Earth and Planetary Science Letters, 2022 - Elsevier
Arc basalts are oxidized relative to mid-ocean ridge basalts; however, the mechanism
through which arc basalts gain this elevated oxidative state is debated. This observation has …
