Zusammenfassung:[Display omitted] •GMS suite of Barberton emplaced in a short period of time from 3110 to 3105 Ma.•GMS magmas are petrologically diverse but isotopically homogeneous, with εHf ~ −2.•GMS magmas formed by partial melting of (i) grey gneisses and (ii) enriched mantle.•Cratonization of the Kaapvaal occurred by pervasive melting of the lithosphere to form a range of granitic melts.
