A melting experiment has been made on a natural lherzolite (spinel lherzolite, KLB‐1) at 20 GPa and 2160°C under hydrous conditions. The stable phase assemblage is liquid, garnet, and modified spinel, which is replaced by phase B above the melting temperature of modified spinel, and garnet is the liquidus phase at this pressure.
