Effect of shallow-level contamination on the helium isotope systematics of ocean-island lavas
The bimodal distribution of helium isotope ratios in ocean-island lavas has provided powerful constraints on the composition and evolution of the Earth's mantle. 'High-3He hotspot' ratios (3He/4He greater than in mid-ocean-ridge basalt, MORB) found on Hawaii and Iceland are thought to...
