Space-time relation of post-collisional granitic magmatism in Santa Catarina, southern Brazil: U-Pb LA-MC-ICP-MS zircon geochronology of coeval mafic-felsic magmatism related to the Major Gercino Shear Zone
(ELSEVIER SCIENCE BVAMSTERDAM, 2012)
LA-MC-ICP-MS U-Pb zircon dating was performed on syntectonic, early post-collisional granitic and associated mafic rocks that are intrusive in the Brusque Metamorphic Complex and in the Florianopolis Batholith, major ...
U-Pb zircon in situ dating with LA-MC-ICP-MS using a mixed detector configuration
(Academia Brasileira de Ciências, 2012)
The LA-MC-ICP-MS method applied to U-Pb in situ dating is still rapidly evolving due to improvements in both lasers and ICP-MS. To test the validity and reproducibility of the method, 5 different zircon samples, including ...
Thermochronology and exhumation history of the basement and sediments of the NNE border of the Paraná basin, Brazil
(2020-04-01)
Combined zircon fission-track (FT) and U–Pb dating were used to obtain correlated cooling ages and tectonic processes in the eastern border of the Phanerozoic Paraná Basin, a large cratonic sedimentary basin in South America ...
In situ isotopic analyses of U and Pb in zircon by remotely operated SHRIMP II, and Hf by LA-ICP-MS: an example of dating and genetic evolution of zircon by 176Hf/177Hf from the Ita quarry in the Atuba Complex, SE BrazilAnálises in situ de U e Pb em zircão por SHRIMP II por controle remoto e de Hf por LA-ICP-MS: um exemplo de datação e da evolução genética de zircão através da razão 176Hf/177Hf em amostra da pedreira Ita no Complexo Atuba, SE Brasil

Idades U-Pb de zircão detrítico da sequência metassedimentar superior na região do Greenstone Belt de Guarinos, Goiás
(2017-09-01)
At the north portion of the Archean Block of Goiás occur two greenstone belts (Guarinos and Pilar de Goiás) covered by a younger metasedimentary sequence, attributed by different authors to the Araxá Group and by other to ...
