The Upper Mantle Beneath Iceland

The gravity field of Iceland, when studied in relation to seismic estimates of crustal thickness, suggests the presence of a substantial mass deficiency within the underlying upper mantle. An interpretation in harmony with the recently discovered delays in P-arrivals at Reykjavik is that there is la...
