TL;DR: The role played by structures such as shear zones in experiments show that fluid-absent melting begins at nearsolidus collecting and transporting melts from their original conditions, around 700°C, promoted by participation of retrogressive sources to midand upper-crustal environments, has phengitic muscovite in the reaction Mus + Kf ± Qz = melt ± been an important field of study as discussed by the authors.

TL;DR: In this article, the authors proposed a geotectonic model for the Sao Gabriel block and the eastern margin of the Rio de la Plata craton, which showed the existence of Meso/Neoproterozoic juvenile oceanic crust and island arc rocks during the Brasiliano orogenic events.

TL;DR: The age of a basement gneiss of the Dom Feliciano Belt along the coast of Rio Grande do Sul has been determined by zircon U-Pb SHRIMP to be about 2.08-Ga for the K-granitic magmatism and 800-590-Ma for the associated low-angle and sub-vertical shear zone deformations as discussed by the authors.

TL;DR: In this paper, the provenance of dust trapped in the Antarctic ice and sediments collected along a ∼4000 km latitudinal band from arid and semi-arid terrains in southern South America is investigated.

TL;DR: The Dorsal de Cangucu Shear Zone (DCSZ) is part of a strike-slip fault system showing trends parallel to the Neoproterozoic Dom Feliciano Belt in southern Brazil as discussed by the authors.
