Central Pacific. Older seamounts uplifted if plate motion carries them over mantle hot spots. A depth-anomaly map reveals several volcanic chains now located on younger hot-spot swells. Uplift is estimated by comparing the observed depth of seamount summit or the observed stratigraphic section in an atoll with that predicted assuming standard subsidence of the sea floor after the seamount formed. The observed uplifts of the Cretaceous seamounts near Hawaii and of the Tuamotu atolls put a limit on when the Hawaiian and Society swells formed at their present localities of maximum elevation. The swells must have developed within the past several million years and probably formed at the same time as did the younger volcanic edifices on their summits.--Modified journal abstract.
