- Abstract:
- There is currently considerable controversy about the origin of oceanic intraplate volcanism. Some believe that it is caused by plumes that rise from deep in the mantle to interact with the base of the plates. Others suggest it is the plates themselves that provide the necessary pathways for magmatic material to reach the surface. One problem that is making it difficult to determine whether plumes exist or not is that the crustal and upper mantle structure of intraplate volcanoes and their associated topographic swells is poorly known. In this proposal, UK scientists will be involved in the first seismic refraction survey of the Cape Verde islands. The islands form an arc of oceanic volcanoes that are located at one of the world's largest swells. Results from the survey will allow us, for the first time, to quantify to contribution of the crust and upper mantle structure of the islands themselves to surface observables such as gravity and geoid, heat flow and seafloor topography and isolate the effects of deeper processes such as those associated with a mantle plume.
