Ontong Java and Kerguelen Plateaux: Cretaceous Icelands?

Together with Iceland, the two giant oceanic plateaux, Ontong Java in the western Pacific and Kerguelen/Broken Ridge in the Indian Ocean, are accumulations of mafic igneous rock which were not formed by ‘normal’ seafloor spreading. We compare published geochronological, crustal structure, and subsidence results with tectonic fabric highlighted in new satellite-derived free-air gravity data from the three igneous provinces, and conclude that existing evidence weighs lightly against the Ontong Java and Kerguelen plateaux originating at a seafloor spreading centre. <br/

The PLATES 2018 Atlas of Plate Reconstructions (550 Ma to Present Day), PLATES Progress Report No. 394-0219

This atlas presents plate reconstructions from 550 Ma to the present-day derived by the PLATES Project, Institute for Geophysics, The University of Texas at Austin. The atlas was made possible through the scientific contributions of many researchers, from UTIG and from other institutions. Their efforts are highly appreciated by the members of the PLATES research team. The atlas was created using the PaleoGIS (paleogis.com) for ArcGIS plate reconstruction software by The Rothwell Group, L.P., and the GPlates (http://www.gplates.org/) plate reconstruction software.
