It consists of three main layers: crust, mantle and core. Geophys Res. (2015) reveal large depressions of the 410-km discontinuity beneath all the archipelagos and a raised 660-km discontinuity close to the MAR and propose that a large hot plume reaches the base of the MTZ in the central-south Atlantic without penetrating it. This inference is supported by whole-mantle tomography models, which find broad low-velocity anomalies in the lower mantle below the Central-East Atlantic.

Shear-wave splitting results (Schlaphorst et al., 2022) find perturbed, small-scale heterogeneous orientation patterns below Madeira ad global RFs whereas precursors studies (e.g., Houser et al., 2008; Lawrence and Shearer, 2008; Deuss, 2009) detect a slightly thinned or close-to-average MTZ thickness, supporting the plume theory. Granite is the most well-known igneous rock in the world. 484, 154167. The presence of a plume beneath the archipelago is also supported by new shear-wave splitting measurements (Schlaphorst et al., 2022), which show a small-scale complexity of the mantle flow pattern in the Canary Islands and suggest that it may be perturbed by a rising upwelling.
