3 Nature and Evolution of the Archean Crust of the São Francisco Craton 33 rocks (Minas Supergroup) ranging between and Ga, and one zircon core is. The Archean rocks crop out mainly in two large areas in the southern and northern portions of the craton, surrounded and/or in tectonic contact with Paleoproterozoic orogenic belts.
The ancient substratum is essentially composed of medium- to high-grade gneissic-migmatitic rocks including TTG suites and coeval granite-greenstone associations Cited by:  Understanding the construction and stabilization of Archean continental lithosphere has important implications for models of tectonic and thermal regimes in the early Earth, as well as for the subsequent evolution of continents.
We provide new constraints for the amalgamation and stabilization of the eastern Kaapvaal craton in the vicinity of the Barberton greenstone belt Cited by: Ashwal, L.D. and J.L. Wooden (). Isotopic evidence from the eastern Canadian shield for geochemical discontinuity in the Proterozoic mantle.
