Graduation (Geology) at Geosciences Institute, Universidade de São Paulo - USP (1974), master's (1978) and Ph.D. at USP (1985). His main research activities focus on Geochronology and Geotectonics, with emphasis on the Sao Francisco and Amazonian cratons (Archean and Proterozoic crustal evolution, including petrogenesis and tectonics of Proterozoic mafic dikes).

The Tectono-magmatic Lull has been proposed for a time interval (2.3-2.2 Ga), assuming that continental magmatism (plume and arc magmatism) and orogenic activity significantly decreased at a global scale. The Paleoproterozoic dynamics combine periods of active and quiescent geologic processes that are recorded worldwide. However, there is a polarization of views concerning whether the pro…
The core goal of this project is to characterize the tectonic evolution of the Rio de la Plata Craton (RPC), the development of the adjacent fold belts, and the interaction with other continental fragments during the development of W Gondwana. Two main lines of integrated action are planned: (i) the application of new geochronological-isotopic techniques using the enhanced instrumentation…
The project deals with paleocontinental reconstructions between cratonic fragmentes (e.g., São Francisco and Rio de la Plata cratons, North China craton). The strategy approach for this goal is based on field workshops with in key geologic areas in the Precambrian shield of South America and China toward the geologic correlations in time and space.

This proposal aims the cooperation of Prof. Mike Hamilton (University of Toronto/Dept of Earth Sciences), Director of the Jack Satterly Geochronological Laboratory in the sampling and U-Pb baddeleyite dating of two Precambrian Mafic Dyke Swarms in the Uruguayan Shield. The study has an important bearing in the geodynamic model of the Rio de La Placa Craton in the Proterozoic which is the …
Zircon U-Pb-Hf and geochemical data provide new clues for a juvenile TTG segment in the Mineiro belt, outlined by published information about the nearby 2.35 Ga Lagoa Dourada suite. The Resende Costa Orthogneiss and coeval rocks yield U-Pb crystallization ages from 2351 ± 48 to 2317 ± 16 Ma and coherent Sm-Nd TDM ages between 2.3 and 2.5 Ga. These rocks show µNd(2.35Ga) and µSr(2.35Ga) va…
