Genesis of Hawaiian lavas by crystallization of picritic magma in the deep mantle

Nature Communications, 2023
Here the authors demonstrate that Hawaiian lavas are formed by partial melting of mantle peridotite with subsequent fractionation of clinopyroxene and garnet in the deep magma chamber (90 km) and reequilibration with harzburgite at a shallower depth (
