Models of formation of basaltic crust at mid-ocean ridges by adiabatic upwelling of fertile mantle lherzolite require knowledge of phase relations and phase compositions during melting at appropriate pressures. Spinel + plagioclase lherzolites are found among peridotite samples from the ocean floor and ophiolitic exposures. At low pressure (<1.2 GPa) the five-phase assemblage (olivine + orthopyroxene + clinopyroxene + plagioclase + spinel) is present at the anhydrous lherzolite solidus. New...[Show more]
