Lavas from Heard Island, located on the Kerguelen Plateau in the southern Indian Ocean, exhibit the largest range (e.g., 87Sr/86Sr=0.7047–0.7079) of isotopic compositions yet observed on a single oceanic island. Isotopic compositions are well correlated and are accompanied by systematic changes in i...
