Summary:

Results of new magmatic helium isotopic compositions have been reported from phase II of the Hawaiian Scientific Drilling Project (HSDP2), which sampled Mauna Kea volcano to a depth of 3098 m below sea level. The magmatic (sup 3)He/(sup 4)He ratios range from 6 to 24.7 times atmospheric (Ra). The correlations of helium with major elements, trace elements and isotopes indicated that Mauna Kea isotopic variability is caused by heterogeneities within the upwelling plume.
