The reactivation of the Brazilian Platform during the Mesozoic influenced strongly the geological configuration of the south and southeast of Brazil, resulting in the opening of the South Atlantic and the generation of the marginal basins that host important volumes of hydrocarbon deposits.One of the major manifestations of this reactivation is the expressive magmatism of Cretaceous age, …
The visit of Dr. Higgins will aim quantitative textural measurements in basaltic samples from the Paraná Magmatic Province. These studies have the potential to unravel the complex evolutionary processes, such as, magma mixing, polybaric crystallization, heterogeneous nucleation rates, among many others. (AU)
The reactivation of the Brazilian Platform during the Mesozoic had a strong influence on the present geological configuration of south and southeast Brazil, resulting in the opening of the South Atlantic and the generation of the marginal basins that today host important volumes of hydrocarbon deposits. The magmatism related to this reactivation is expressive, corresponding to the second …
The project aims investigating the large number of alkaline rock occurrences present in the South American platform. This magmatic activity is found in and around the Paraná Basin in Brazil, Paraguay, Bolívia and Uruguay, but it is more concentrated in the former two countries. It started in the Permian- Triassic (250-240 Ma) and lasted up to the Oligocene (~39 Ma) times. Apart from its c…

The detailed study of mafic mineral phases in igneous rocks, involving physical and chemical aspects, has been very important for understanding petrological processes and estimating intensive parameters such as temperature, pressure, oxygen fugacity and silica activity of different magmatic types. The study mainly involves petrographic characterization, mineral chemistry analyzes using te…
The progressive evolution of petrological knowledge and the methodological advances of the last decade have contributed significantly to the study of igneous petrology at submicroscopic microscopic scales, allowing the identification of processes and mechanisms. In this sense, detailed petrographic observations and textural and compositional interpretations have been shown to be fundament…
The main goal of the project presented here is the petrological study of a suite of xenoliths found in kimberlites and related rocks in different regions of the Brazilian platform by gathering petrographic information on the lithotypes present and to establish mineralogical and textural (faciological) variations of xenoliths in intrusions of kimberlitic fields of Minas Gerais, Goiás, Para…
The aim of this research proposal is to investigate the characteristics and effects of the metasomatic fluids related to the fenitization process that took place at the contacts between ultramafic rocks and carbonatites from different Brazilian occurrences: Salitre, Tapira, Araxá (Alto Paranaíba) e Jacupiranga (Arco de Ponta Grossa) complexes. Studies on alkaline-carbonatite units that di…

This proposal for a BEPE scholarship is part of the ongoing collaborative studies among researchers from USP and University of Alberta (CAN). The student, Julia C. Bandeira Lino de Souza, will focus her undergraduate conclusion monograph on studying mantle xenocrysts from two specific hypabyssal intrusions in the province: Pântano (Limpeza-18) and Forca (Forca-01). The aforementioned sele…
Geothermobarometry is an important tool to study intensive parameters of igneous rocks and understanding crystallization conditions, evolution and emplacement of magmas. Physical conditions such as temperature, pressure, oxygen fugacity, silica activity, NaCl activity can be rebuilt with the identification and chemical analysis of the magmatic paragenesis. The determination of these param…
