Hot and Heterogenous High‐ 3 He/ 4 He Components: New Constraints From Proto‐Iceland Plume Lavas From Baffin Island
International audience Key Points: Baffin Island-West Greenland high-3 He/ 4 He lavas are more geochemically depleted than any other high-3 He/ 4 He lavas globally. The isotopic composition of the high-3 He/ 4 He mantle source in the Iceland plume has evolved through time. Baffin Island and We...
