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...
Abstract Dispersion of low‐temperature thermochronologic data from nine samples collected on a deformed paleosurface preserved the Cuevas range (Central Andes) can be exploited to unravel complex thermal histories. The yielded that have both intersample and intrasample dispersions; set includes apatite fission‐track ages (180–110 Ma), mean track lengths (11–13 μm), helium (10–250 zircon (180–348 Ma). We ran inverse history models for each sample reveal spatial variations Miocene reheating...
A margem continental brasileira denota estruturas geomorfológicas moldadas durante vários episódios de atividade tectônica iniciados no Neoproterozoico. Com o objetivo estabelecer um modelo história termotectônica para a brasileira, foi realizada integração e reinterpretação dos dados traços fissão em apatita (TFA) disponíveis ao longo toda continental. As idades TFA variam ~385-10 Ma. Os revelam que caracterizada por pelo menos três eventos térmicos após Ciclo Brasiliano: Cretaceo Inferior,...
Through the joint use of apatite fission tracks (AFT) and (U–Th)/He analysis in (AHe) zircon (ZHe), we evaluate thermotectonic evolution Sul-Rio-Grandense Shield (SRGS), southernmost Mantiqueira Province, Brazil. Formed during assembly West Gondwana (Neoproterozoic), shield comprises four tectonostratigraphic terranes separated by regional faults shear zones. The central eastern present Mesozoic AFT ages, whereas western terrane ages are mostly late Paleozoic. AHe show considerable...
Two major magmatic pulses of the granitic Florianópolis Batholith in Santa Catarina State, southern Brazil, occurred between 613±5Ma and 595±5 Ma, during Neoproterozoic Brasiliano Cycle. These ages were obtained by U-Pb isotopic determinations with sensitive high mass-resolution ion microprobe on igneous zircons from Pedras Grandes Suite State. Euhedral remained unaltered close to a fluorite vein deposited at 180?C or more. suggest northern limit for Suite, explaining spatial relationship...
Foi realizada a reconstrução da história de denudação e evolução tectônica margem continental do nordeste brasileiro na região Rifte Recôncavo-Tucano-Jatobá, usando termocronologia por traços fissão em apatita modelagem térmica. O rifte Recôncavo-Tucano-Jatobá é um sistema meio-grabens Cretáceo Inferior, separado altos embasamento evoluiu como abortado durante ruptura Gondwana abertura Atlântico Sul. As idades variam 336 ± 51 140 14 Ma, o que implica uma prolongada espacialmente variável...
