View article: Crustal to mantle melt storage during the evolution of Hawaiian volcanoes
Crustal to mantle melt storage during the evolution of Hawaiian volcanoes Open
As the Pacific Plate migrates over the mantle plume below Hawaiʻi, magma flux decreases, resulting in changes in eruptive volume, style, and composition. It is thought that melt storage becomes deeper and ephemeral with the transition from…
