WebThe fields of study he is best known for: Patrice Rey mainly investigates Lithosphere, Mantle, Earth science, Crust and Continental crust. Lithosphere and Geophysics are frequently intertwined in his study. His Mantle research incorporates elements of Flood basalt, Supercontinent and Archean. His study in Crust is interdisciplinary in nature ... WebFlood basalts in the oceans are known as oceanic plateaus, and include the Ontong Java plateau of the western Pacific Ocean and the Kerguelen Plateau of the Indian Ocean. The narrow vertical conduit, postulated to connect the plume head to the core-mantle boundary, is viewed as providing a continuous supply of magma to a hotspot.
