Abstract

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 largest continental volcanic province in Planet Earth in exposed area (Paraná-Etendeka Magmatic Province) and one of the most remarkable associations of alkaline rocks, to which important mineral deposits are related. Although clearly linked temporal and spatially, the petrologic processes that generated the tholeiitic and alkaline magmatism were rarely the subject of integrated studies; similarly, the geological and geophysical approaches in both the regional and detail scales are also in need of a better integration. In this project, some of the more active research groups that currently study the mesozoic-cenozoic magmatism in south and southeast Brazil will work in association, aiming to solve some of the currently most relevant problems, especially the stratigraphy and chronology of magmatism, the physical processes related to magma emplacement and extrusion, the conditions of magma generation in the underlying mantle and crust, and the geodynamic significance of the magmatic events. To that purpose, a wide variety of tools will be employed, including some classical (e.g., whole-rock and mineral elemental and isotope chemistry; Ar-Ar dating) and others that are either new or will be for the first time widely used for these rocks (U-Pb dating; Lu-Hf isotopy; magnetotelluric surveys; detailed structural geology combined with anisotropy of magnetic susceptibility and/or gravimetry; experimental petrology).
