Lithospheric Features of the São Francisco Cratone suture zones during the Gondwana amalgamation. Modeling of gravity anomalies with some seismic constraints indicates a relatively low-density lithospheric mantle for the SFC, despite higher Pn velocity, which is consistent with a Fe-depleted, buoyant lithosphere, which helps preserve the cratons’s

Nature and Evolution of the Archean Crust of the São Francisco Cratony ancient continental crust (˃3.5 Ga) exist, particularly in the northern portion of the craton. Mesoarchean events are episodic between 3.6–3.3 and 3.2–2.9 Ga, as for the Neoarchean (2.8–2.6 Ga) in both cratonic portions. This isotopic record indicates a protracted Archean history for the São Franc
