(a) Electrical conductivity cross-section; (b) and (c) are temperature and density, respectively, and are extracted from the results inverted from the Rayleigh wave dispersion, surface heat flow, geoid height and topography by the Bayesian inference approach24,42,43. The effective viscosities in (d) to (f) are transformed from eq. (5) with the associated parameters in Table 1. The four triangles in (a) and (d) mark the locations for comparison in Fig. 5.
