Research Line

Marine and Coastal Geology 

It involves the study of the tropical coastal and marine environments, focusing on geomorphology, stratigraphy and morphodynamics, in order to reconstruct the evolution of northern coast of Brazil during the Quaternary.

Area of concentration: Geochemistry 

 

Research line:

Geochronology and Isotope Geochemistry

It comprises the isotopic studies by the radiometric methods Pb-Pb in zircon, Sm-Nd and Rb-Sr aiming at the elaboration of geodynamic models for the evolution of crustal segments in the Precambrian and Phanerozoic periods of South America and the western part of Africa. In parallel, it involves the isotopic studies applied in the exploration of hydrocarbons and in the investigation of the genesis and evolution of mineral deposits, as well as the use of isotopic tools in the investigation of environmental problems.

Research Line

Mineralogy and Geochemistry 

It involves the use of techniques of identification of crystalline and amorphous (DRX, IV, ATD / TG, optical and electronic microscopy, Mossbauer, Raman, etc.) and chemistry (AAS, FRX, MEV / SED, chromatography, mass spectrometry, among others) substances in the study of minerals, rocks, soil, lateritic materials, ores, archaeological artifacts and from the historical archeology, products of synthesis, among others, aiming at the understanding of formation, production and evolution, geological application, metallogenic, industrial, human occupation, environmental; synthesis of new materials and its application. The main focus, when pertinent, is the Amazonian context. The researches concentrate in: mineral and new products synthesis; laterites and lateritization and associated mineral deposits; archeometry: lytic and ceramic artifacts and black ground soils; gem minerals and mineral handicraft.

Research Line

Crustal evolution and metallogenesis

The line of Research in Crustal Evolution and Metallogenesis is directed at the understanding of the geological evolution of the cortical segments in the Brazilian territory, with a major focus on the Amazonian Craton, the orogenic belts that surround it and the northwest of Borborema Province, including the São Luis Craton, with regional and local scales. The main objective of this line implies the definition of the processes that control the genesis of the rocks and the associated mineral deposits in space and time, in order to use the knowledge to understand the geodynamics, understand the conditional processes by the Earth formation and discuss and establish models of crustal evolution that could even subsidize the mining exploration. The methods and techniques focused in this topic are varied and involve: geological mapping, stratigraphy, structural geology / tectonics, including microtectonics, petrology, geochronology, isotopic geochemistry, geochemistry, scanning electron microscopy (SEM), electron probe micro analysis (EPMA), geothermobarometry, microthermometry, sedimentology, geophysics, remote sensing, mineralization control, typology and genesis of mineral deposits, including supergenic formations such as laterites and gossans (bauxite, Fe, Au, EGP, Ni, Mn, phosphates, others).
