Abstract

Oceanic plateaus are vast areas (> 0.1 × 106 km2) of overthickened oceanic crust (up to, and sometimes > 30 km) that are widely interpreted to have formed by decompression melting of hot mantle plumes. Oceanic plateaus have formed throughout most of Earth's history and, due to their excess crustal thicknesses, are difficult to subduct; typically, their uppermost sections are accreted to continental margins. In addition to providing a means of preserving sections of these plateaus in the geological record, the accretion of oceanic plateaus has been an important contributor to crustal growth throughout Earth's history.
