A multichannel seismic study of lithospheric flexure across the Hawaiian–Emperor seamount chain

Abstract

Existing models assume that the thickened crust beneath seamounts is the result of a surface volcanic load flexing an elastic plate. New results suggest that flexed oceanic crust beneath the Hawaiian–Emperor seamount chain is underlain by a 4-km thick deep crustal body. We intepret the body as a deep crustal sill complex associated with the tholeiitic stage of volcano building along the chain.
