Diverse magma storage and major and volatile magma composition: What are the implications on the eruptive style across a volcanic arc? An example of the Lesser …
Understanding variations in eruptive style and defining the processes and controls on
different eruption styles is particularly important at arc volcanoes. This is due to the range of …

Machine learning thermobarometry and chemometry using amphibole and clinopyroxene: a window into the roots of an arc volcano (Mount Liamuiga, Saint Kitts)
The physical and chemical properties of magma govern the eruptive style and behaviour of
volcanoes. Many of these parameters are linked to the storage pressure (P) and temperature …

Subducting volcaniclastic-rich upper crust supplies fluids for shallow megathrust and slow slip
Recurring slow slip along near-trench megathrust faults occurs at many subduction zones,
but for unknown reasons, this process is not universal. Fluid overpressures are implicated in …

Serpentinite-derived slab fluids control the oxidation state of the subarc mantle
Recent geochemical evidence confirms the oxidized nature of arc magmas, but the
underlying processes that regulate the redox state of the subarc mantle remain yet to be …

Slab dehydration and potassium-lithium recycling in the forearc indicated by potassium and lithium isotope compositions of exhumed metabasites
Slab dehydration at subduction zones has broad implications for arc magmatism, mantle
heterogeneity and elemental cycling. We present the petrography, mineral chemistry and …

Boron isotopes in boninites document rapid changes in slab inputs during subduction initiation
How subduction-related magmatism starts at convergent plate margins is still poorly
understood. Here we show that boron isotope variations in early-formed boninites from the …

Mg-Ba-Sr-Nd isotopic evidence for a mélange origin of early Paleozoic arc magmatism
In recent years, the mélange model has been increasingly considered as an important way
to transfer slab components to arc sources in modern subduction zones. This model differs …
