From Mantle to Cratonic Reactivation: Petrological Insights from Kimberlites and Lamproites of the São Francisco Craton, Brazil

Minerals
This study redefines the Nordestina Kimberlite Province (PKN), in the northeastern sector of the São Francisco Craton (SFC), as a composite kimberlitic–lamproitic system that hosts two genetically distinct magma types: (1) the primitive Braúna kimberlite
