- •
CE-boninite and boninite-series felsic dikes of New Caledonia yield Early Eocene 40Ar/39Ar and U–Pb zircon ages respectively
- •
Geochemical modeling suggest source enrichment by subduction-derived fluids and MORB-like melt component
- •
CE-boninite magma may have been in equilibrium with enstatite-bearing gabbro cumulates of the Peridotite Nappe
