Fragments of ancient continental lithosphere, entrained in the shallow oceanic mantle, have been found in a number of locations in the Southern Hemisphere. Isotopic analyses of material from Quaternary volcanic centres in Hispaniola indicate that the lavas are derived from an ancient lithospheric fragment with affinities to the supercontinent Gondwana.
