Boundary‐Layer Melts Entrapped as Melt Inclusions? The Case of Phosphorus‐ and CO ₂ ‐Rich Spinel‐Hosted Melt Inclusions from El Hierro, Canary Islands

Editorial: Crystal Archives of Magmatic Processes

“…Melt inclusions trapped by growing crystals provide distinct records of magmatic evolution (Kent et al, 2010). An important assumption is that entrapped melts are representative of the bulk environment and not liquid boundary layers created during fast crystal growth (Baker, 2008;Longpré et al, 2020). Moreover, the effects of post-entrapment crystallisation within inclusions need to be carefully assessed, as well as the effects of experimentally reheating inclusions prior to microanalysis (Nielsen, 2011).…”
