ABSTRACT: The Dom Feliciano Belt is an important Neoproterozoic to Cambrian orogenic complex, extending from eastern Uruguay southern Brazil. It comprises a collage of oceanic domains and continental fragments developed between 900 540 Ma the Rio de La Plata, Congo Kalahari cratons. integration field structural data with recent isotopic results has introduced new insights on sources magmatism sedimentary processes. This paper presents review geochronological combined stratigraphic,...
The absence of absolute dating in glacial deposits the Paraná Basin prevents better understanding complete history Late Palaeozoic Ice Age Western Gondwana and climatic change that took place late Carboniferous. In this study, new U–Pb radiometric ages date topmost Itararé Group at 307.7 ± 3.1 Ma (Kasimovian−Moscovian) base post-glacial Rio Bonito Formation 298.8 1.9 (Ghzelian−Asselian). Correlation with other southwestern basins shows end is asynchronous. Supplementary material: Laser...
The Capivarita Anorthosite, formed in an intraplate environment and later metamorphosed under amphibolites facies conditions, is exposed the Dom Feliciano Belt as part of Brasiliano magmatic arc occurs a roof-pedant in, or even intruded by, 0.6 Ga post-collisional granites. In this work, metamorphic minerals were dated using LA-MC-ICP-MS situ method. U–Pb zircon dating yielded age 1573 ± 21 Ma 606 6 Ma, respectively, whereas igneous titanite 1530 33 ages 651 9 601 5 Ma. Lu–Hf model showed...
Zircon U-Pb geochronology was applied to investigate the provenance, depositional ages, and paleogeography of southwestern Gondwana in detrital ash fall sediments from Carboniferous Jurassic succession southern Paraná Basin. Four age populations suggest provenance local distal sources located south, southeast, southwest: (i) Archean Paleoproterozoic zircons Rio de La Plata Craton, Nico Peres Taquarembó terranes; (ii) Grenvillian basement Gondwanides Namaqua–Natal belts; (iii) Neoproterozoic...
