Petrology and geochemistry of Sangeang Api and recent volcanism in the Sumbawa-Flores sector of the Sunda Arc: the response of along-arc geochemistry to subduction processes.
… melting (10-13%) of basaltic underplates. Ultrapotassic magmatism in the Sunda Arc is confined to the rear-arc and characterised by trace-element and isotopic evidence of mantle metasomatism and the influence of slab tear windows. Slab window development has changed the loci and composition …

Igneous life cycles: geochemistry of magma from mantle to surface and back again
… along the Hikurangi subduction zone. Alkaline magmatism at Mountain Pass, CA has attracted attention due to its spatial and temporal association with a REE-rich, economically important carbonatite. However, questions remain about the origins of magma here. We present geochemical data for 121 …
