On the Volcanic and Geodynamic Evolution of the Shatsky Rise and the Louisville Seamount

Creator:

Heaton, Daniel E.

Abstract:

Large igneous provinces (LIPs) and intraplate seamounts reflect of anomalous mantle melting and illuminate interior processes of the Earth. These features are in all ocean basins and show the mantle’s evolution over time, then can provide information on plate tectonic processes, such as plate motion over time, spreading ridge formation,...

Timescales and tectonics of oceanic plateaus : long-term evolution of Ontong Java Nui and Rio Grande Rise

Creator:

Davidson, Peter C.

Abstract:

Oceanic plateaus are regions of overthickened oceanic crust and are often thought to form from the interaction of mantle plumes with oceanic lithosphere. These regions can cover vast areas of the ocean basins and represent a highly elevated magmatic flux relative to normal mid-ocean ridge spreading. Oceanic plateaus are considered...
