Volcanism Isotope ratios

Summary:

The purpose of this study is to trace the contribution of undepleted mantal material to the volcanic rocks on the island of Hawaii via the use of helium isotopes and to test the viability of the "deep mantle plume" hypothesis, that was developed by W. J. Morgan, in this context. In an effort to study the (sup 3)He/(sup 4)He variations, with regard to volcano age and various stages of evolution, samples from Mauna Kea, Hualalai, Mauna Loa, and Kilauea, (listed according to age), were analyzed. Samples from Loihi Seamount, the youngest volcano in the Hawaiian chain after Kilauea, were also analyzed and provided an opportunity to study the earliest stages of Hawaiian volcanism.
