There is a new paper in Earth and Planetary Science Letters that argues that the Ontong Java Plateau in the Pacific Ocean was created by a meteorite impact. The paper is:
Stephanie Ingle and Millard F. Coffin, 2004, Impact origin for the greater Ontong Java Plateau? Earth and Planetary Science Letters. vol. 218, no. 1-2, pp. 123-134 (30 January 2004) In part, the abstract stated: "Geophysical, geochemical, and geodynamic evidence from the province are difficult to reconcile with mantle plume models; absence of an obvious hotspot source or track, minor crustal uplift associated with emplacement, minor total subsidence compared with normal oceanic crust or other oceanic plateaus and submarine ridges, high degrees of melting at shallow, upper mantle depths, low water contents of basalts, enrichment of platinum group elements in basalts, and a ~300 km deep, seismically slow mantle root are more consistent with the consequences of an impacting bolide."
