A possible role for garnet pyroxenite in the origin of the "garnet signature" in MORB

Geochemical data have been interpreted as requiring that a significant fraction of the melting in MORB source regions takes place in the garnet peridotite field. MORBs may be produced by melting of mixed garnet pyroxenite/spinel peridotite sources, and some or all of the "garnet signature"...

Summary:Geochemical data have been interpreted as requiring that a significant fraction of the melting in MORB source regions takes place in the garnet peridotite field. MORBs may be produced by melting of mixed garnet pyroxenite/spinel peridotite sources, and some or all of the "garnet signature" in MORB may be contributed by partial melting of garnet pyroxenite layers or veins.
