Partial melting experiments on a MORB‐like pyroxenite between 2 and 3 GPa: Constraints on the presence of pyroxenite in basalt source regions from solidus location …
M Pertermann, MM Hirschmann - Journal of Geophysical …, 2003 - Wiley Online Library
We present partial melting experiments at 2–3 GPa on a basaltic pyroxenite (G2) similar in
composition to typical oceanic crust. The 3.0 GPa solidus is located at 1310±12° C and the …

Tectonic accretion and underplating of mafic terranes in the Late Eocene intraoceanic fore-arc of New Caledonia (Southwest Pacific): geodynamic implications
This paper deals with the tectonic events that result in the accretion of mafic terranes in the
fore-arc region and a close juxtaposition of ultramafic rocks, low grade and high-grade mafic …
