Fig. 3From: Evolution of the Earth as an andesite planet: water, plate tectonics, and delamination of anti-continent V P structure of the IBM arc and its petrological interpretation. V P and density calculated for the inferred lithologies in the sub-IBM arc crust and mantle are also shown. The calculated V P values (lines) are consistent with the observed V P structure (light area). Note that a density inversion is predicted for the low-V uppermost mantle layerBack to article page
