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 ...
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 ...
Anatectic granites of the Sierras Pampeanas from Córdoba (Argentina): U-Pb SHRIMP and zircon trace element LA-ICP-MS study of diachronic metamorphism and crystallizationGranitos anatécticos de las Sierras Pampeanas de Córdoba (Argentina): edades U-Pb SHRIMP y estudio LAICP-MS de elementos traza en circón de metamorfismo y cristalización diacrónicos
(Sociedad Geológica de España, 2020-05-29)
En este trabajo se aportan nuevos datos de edades U-Pb SHRIMP y análisis in situ LA-ICP-MS de elementos traza de circones provenientes del granito Río de los Sauces, Córdoba, Argentina. A partir de marcadas diferencias ...
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

The temporal evolution of the Mitu group, south-east Peru – first U-Pb age data
(Swiss Society of Mineralogy and Petrology (SSMP)CH, 2009-11)
The Eastern Cordillera of southern Peru formed along a crustal zone that has been active as part of the western Gondwana margin since the middle Paleozoic. The present study investigates the Mitu Group of south-east Peru ...
