The response of the Pacific plate to oceanic island and seamount loads has been used to estimate the distribution of ridge crest and off-ridge volcanism on the plate since the late Jurassic. The most extensive event, forming the Hess rise, Line Islands ridge, Necker ridge, and Robbie ridge, occurred on the Pacific/Farallon and Pacific/Phoenix ridge crests during the interval 90–120 Myr BP (Barremian to Turonian). This event, which extended over a much larger area than comparable volcanism on…

Contrasting geophysical and geochemical signatures of a volcano at the axis of the Wharton Fossil Ridge (N‐E Indian Ocean)
The Styx volcano is a prominent seamount (20–30 km diameter, 2500 m high) located at the axis of the Wharton fossil spreading center (N‐E Indian Ocean), where seafloor spreading stopped 40 Ma ago.…
Volcanism and vertical tectonics in the Pacific Basin related to global Cretaceous transgressions
Pacific seamount volcanism in space and time
SUMMARY Seamounts constitute some of the most direct evidence about intraplate volcanism. As such, when seamounts formed and into which tectonic setting they erupted (i.e. on-ridge or off-ridge) are…
Geological Evolution of the Nauru Basin, and Regional Implications
Leg 61 originally was planned as a study of sedimentary, paleoceanographic, biostratigraphic, petrologic, magnetic, and tectonic problems in the western Pacific ranging back to Late Jurassic time. To…
Planform of mantle convection beneath the Pacific Ocean
The correlation between variations of the bathymetry and of the geoid in the Pacific Ocean suggests that both are the surface expression of mantle convection. The planform of the convection which is…
Isostasy and Tectonic Origins of Pacific Seamounts
Previous studies have shown that the response of the Pacific plate to oceanic island and seamount loads can be used to estimate the distribution of ridge-crest, superswell, and normal mid-plate…

Orogenic processes in the Alpine collision zone
Compressional systems are usually characterized by a positive topography above the sea level, which is continuously modified by the conjugate effects of tectonic contraction or post-orogenic…

The Geology of Hess Rise, Central North Pacific Ocean
The geology of Hess Rise is interpreted from studies of morphology and structure, igneous petrology, sediment lithofacies, seismic stratigraphy, and paleoenvironments. Hess Rise probably formed at a…

A significant fraction of the volcanism on the Earth’s surface cannot be associated with plate margin processes. The mantle plume hypothesis is one explanation for this volcanism. Convective plumes…
