Direct observation of degassing during decompression of basaltic magma
Transitions in eruptive style during volcanic eruptions strongly depend on how easily gas
and magma decouple during ascent. Stronger gas-melt coupling favors highly explosive …

[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) …

Outgassing behaviour during highly explosive basaltic eruptions
Explosivity of basaltic eruptions is related to the efficiency in which exsolved gas can
separate from the melt during ascent, which is controlled by magma permeability. However …
