Critical role of water in the formation of continental crust
Continental arcs are the sites of production of continental crust, but the origin of these
magmatic systems is not well understood. Although a number of processes have been …

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 …

Variable water input controls evolution of the Lesser Antilles volcanic arc
Oceanic lithosphere carries volatiles, notably water, into the mantle through subduction at
convergent plate boundaries. This subducted water exercises control on the production of …

Petrology of the 2020–21 effusive to explosive eruption of La Soufrière Volcano, St Vincent: insights into plumbing system architecture and magma assembly …
Abstract The 2020–21 eruption of La Soufrière, St Vincent began with extrusion of a viscous
lava dome, which was destroyed upon transition to a major explosive phase. Here we …

Eruptive dynamics reflect crustal structure and mantle productivity beneath volcanoes
O Higgins, L Caricchi - Geology, 2023 - pubs.geoscienceworld.org
Volcanoes exhibit a wide range of eruptive and geochemical behavior, which has significant
implications for their associated risk. The suggested first-order drivers of intervolcanic …
