Summary:

Using experiments on peridotite with glass analyses from the Hawaii Scientific Deep Project on Mauna Kea volcano, it is show that a small population of the core samples had fractionated from a peridotitesource primary magma. Samples in the Hawaiian core are consistent with previous suggestions that pyroxenite occurs in a host peridotite, and both contribute to melt production. Primary magma compositions vary down the drill core, and these reveal evidence for temperature variations within the underlying mantle plume.
