This is an abstract of an online journal (Geology) article which presents geochemical compositions of basalts from the Polynesian "superswell" region of the South Pacific. The geochemical data from the basalts, along with their ages, are interpreted as indicating a deep-mantle plume origin and superplume activity in the region as old as 90-150 million years ago. This page also includes information on how to purchase the full text article.
