  • Degassing of the Earth's mantle through magmatism results in the irreversible loss of helium to space, and high 3He/4He ratios observed in oceanic basalts have been considered the main evidence for a ‘primordial’ undegassed deep mantle reservoir. Here we present a new global data compilation of ocean island basalts, representing upwelling ‘plumes’ from the deep mantle, and show that island groups with the highest primordial signal (high 3He/4He ratios) have striking chemical and isotopic… CONTINUE READING
