Hotspot—migrating ridge interaction in the South Atlantic

Nature volume 313, pages 187–191 (1985)Cite this article

Abstract

Short-wavelength geochemical anomalies in the basaltic layer 2A occur along the South Atlantic mid-ocean ridge opposite Ascension, St Helena and Tristan hotspots, further evidence that preferential subcrustal flow channels develop between mantle upwelling zones (hotspots) and migrating ridge axes. Geochemical variability suggests that the plume along these channels would be schlieren-like rather than continuous.
