Post-entrapment modification of volatiles and oxygen fugacity in olivine-hosted melt inclusions
The solubilities of volatiles (H 2 O, CO 2, S, F, and Cl) in basaltic melts are dependent on
variables such as temperature, pressure, melt composition, and redox state. Accordingly …

Exceptional eruptive CO2 emissions from intra-plate alkaline magmatism in the Canary volcanic archipelago
Alkaline mafic magmas forming intra-plate oceanic islands are believed to be strongly
enriched in CO2 due to low-degree partial melting of enriched mantle sources. However …

Tracking the changing oxidation state of Erebus magmas, from mantle to surface, driven by magma ascent and degassing
The conventional view holds that the oxidation state of a mantle-derived degassed magma
reflects its source. During magma ascent and degassing the oxidation state is thought to …
