TL;DR: In this paper, the authors reported new U-Pb data from the southern sector of the Brasilia belt in order to provide temporal limits for the deposition and ages of provenance of sediments accumulated in passive margin successions around the south and southwestern margins of the Sao Francisco Craton, and date the orogenic events leading to the amalgamation of West Gondwana.

TL;DR: The Late-Cretaceous Alto Paranaiba Igneous Province (APIP) comprises a variety of ultrapotassic rock types, including kimberlites, lamproites and large volumes of kamafugites, in addition to a number of carbonatite-bearing plutonic alkaline complexes as mentioned in this paper.

TL;DR: In this article, the authors present a new evolution model for the Araxa Group in its type area, the southern segment of the Neoproterozoic Brasilia Belt, Minas Gerais, Brazil.

TL;DR: In the southern Brasilia belt of central Brazil, prominent east-verging systems of stacked nappes caused the thrusting and tectonic interleaving of metasedimentary rocks of different provenance, age and metamorphism as discussed by the authors.

TL;DR: In this article, the Bambui Group shows two facies associations: (1) massive diamictites; (2) sandstones, conglomerates, laminated siltstones and carbonates association.
