- •
Coexistence of tholeiitic MORB & alkaline OIB in the Manipur Ophiolite Complex, northeast India.
- •
MORB generated by partial melting (∼20%) of depleted upper mantle within spinel stability facies zone.
- •
5–10% partial melting of enriched mantle or plume material at garnet facies stability zone is responsible for OIB-type.
