Fig. 5: Vote maps of mantle tomography models.
From: Seismological expression of the iron spin crossover in ferropericlase in the Earth’s lower mantle
Variable depth vote maps for fast (>+1σ from the mean), and slow (<−1σ from the mean) mantle for all a 4 P-wave and b 4 S-wave tomography models (see Methods) considered here. In general, lower mantle vote maps of fast velocity regions reveal subducted slabs, and slow maps reveal plumes and antipodal large low shear wave velocity provinces (LLSVPs). In this map view, the P-wave model vote maps appear less coherent than the S-wave model vote maps in the fast velocity regions of the mid-mantle. Colour gradients from ref. 73.
