Mantle source characteristics and magmatic processes during the 2021 La Palma eruption
Abstract The 2021 eruption of La Palma (September 19-December 13) was the first
subaerial eruption in the Canary Islands in 50 years. Approximately 0.2 km 3 of lava erupted …

Olivine chemistry reveals compositional source heterogeneities within a tilted mantle plume beneath Iceland
Abstract High-Fo olivine (Fo= Mg/(Mg+ Fe) mol%) is an ideal proxy for establishing the
compositions of primary melts and their mantle sources. This has been exploited in …

Volcanic plumbing filters on ocean-island basalt geochemistry
Ocean-island basalts (OIBs) are considered to be messengers from the deep mantle, yet the
filtering effect of the plumbing systems that bring OIB melts to the surface remains poorly …
