The thickness and seismic S-wave velocity of the UICL and northern India are similar to what is found beneath Proterozoic and Archean cratons in global tomographic models (e.g., Lu et al., 2019). Thus, we identify the UICL in model FWEA23 as ancient cratonic lithospheric mantle that is compositionally buoyant with high viscosity (Jordan, 1988).
