Abstract

The island of Kauai has always been interpreted as a single shield volcano, but lavas of previously correlated reversed-to-normal magnetic-polarity transitions on opposite sides of the island differ significantly in isotopic composition. Samples from west Kauai have 87Sr/86Sr < 0.7037, ϵNd ≥ 6.14, and 206Pb/204Pb > 18.25; samples from east Kauai have 87Sr/86Sr > 0.7037, ϵNd ≤ 6.14, and 206Pb/204Pb < 18.25. Available data suggest that a younger eastern shield grew on the collapsed flank of an older western one.
