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 Neoproterozoic evolution of the Paranapanema and São Francisco Blocks is part of the convergence history of the Farusian-Goiás Ocean. The efforts for the paleogeographic reconstruction of this scenario involve the partial arrangement of the continental margin from eastern Rodinia and western Gondwana. This scientific project seeks to establish the constitution and the boundaries of th…
The evolution and provenance of the crustal materials formed at the southwestern edge of Gondwana is the main purpose of this Project. The role of crustal recycling during the Ordovician magmatism of the Famatinian Orogen and also the geodynamic model for the magmatism of the Middle-Upper Devonian to Mississippian in Pampean Orogen are the main targets. The Paleozoic magmatic rocks from C…
The Brasília Orogen, in the southern marginal portion of the São Francisco Craton, records the collision between the Sanfranciscana and Paranapanema neoproterozoic tectonic plates. This orogen, organized in the Socorro-Guaxupé Nappe and Andrelândia, Carrancas and Lima Duarte nappe systems, is the object of study of the present research proposal. The recognition of paleotectonics features …
This project aims to contribute to the understanding of the tectonic and geodynamic evolution of southwestern Gondwana, from its amalgamation in the Neoproterozoic to its break-up in the Cretaceous. For this, the research will focus on the long-term tectonic activity of the network of shear zones of the Kaoko Belt in northwestern Namibia. The deformation history of these structures during…
The Southern Brasília Orogen is a record of convergence within the margins of the SãoFrancisco and Paranapanema paleoplates, recognized as a neoproterozoic subduction andcollision tectonic wedge located at the edge of the São Francisco Craton. From the Ediacaran(635Ma) it began to set up a system of nappes from high to ultra-high temperature and highpressure transported along the craton e…
Isotopic studies of the inner domain from the Paraguay Belt The structural setting, the composition and age of magmatic rocks and the sedimentary provenance from the Paraguay Belt inner domain (allochthonous?) are approaches that aim to distinguish, in this domain, geological signatures from active margin or asymmetric rift distal zone. The search of this paleogeographic configuration pla…
Paleogeographic reconstructions of pre-Cambrian continental masses configurations are of great importance for the understanding of the geological and life evolution. Paleocontinents covered by thick sedimentary packages and from which the Geology is poorly known, usually are not considered in the paleogeographic sketches of Rodinia-Gondwana evolution, where the paleomagnetic data achievem…

The aim of this project is a collaborative work with Professor Andreas Möller at The University of Kansas, USA. Professor Möller is director of the KU LA-ICP-MS Geochronology laboratory, which is equipped with a Thermo Scientific Element2 ICP-MS coupled with a 193nm ArF Excimer laser ablation system. He is an expert in geochronology, especially on dating metamorphic events and reconstruct…
Zircon is the most used mineral in studies of metasedimentary rocks provenance because of its resistance to intemperism, diagenesis and metamorphism. Nowadays, studies of the U-Pb and Lu-Hf isotopic system are the main tools used in such studies, because the first separates crystal populations by age and the second yields information about crustal and mantle contributions.Prof. Dr. Hawkes…
