The evolution of He Isotopes in the convecting mantle and the preservation of high He-3/He-4 ratios

The evolution of He Isotopes in the convecting mantle and the preservation of high He-3/He-4 ratios

A key requirement for any model of mantle evolution is accounting for the high 3He/4He ratios of many ocean island basalts compared to those of mid-ocean ridge basalts. The early, popular paradigm of primitive, undegassed mantle stored in a convectively isolated lower mantle is incompatible with geo...
