SUMMARY:

The Passa Quatro and Itatiaia Alkaline Complexes (ACPQ-ACIT) comprise two batholiths located on the borders between the Rio de Janeiro, Minas Gerais, and São Paulo states. Proterozoic basement rocks, represented by gneisses and migmatites of the Ribeira and Brasília belts, separate ACPQ-ACIT. The alkaline complexes represent about 435Km2 of plutonic to hypabyssal lithotypes, migrating through dykes and sills embedded in Brazilian failure zones reactivated during the Gondwana rupture. The Passa Quatro complex is to the West of Itatiaia and, in general, has a rounded elliptical shape, with an E-W trending, while Itatiaia massif appears to run SE-NW trending. These rocks of Mesozoic-Cenozoic age represent excellent materials for magnetometric studies. The Geological Survey of Brazil (CPRM) provides data from the São José do Rio Preto-Resende project that will be used to propose models for the ACPQ-ACIT emplacement and considering the absence of a primary component for the Passa Quatro. In addition, the chance of connection between the massifs in depth can be evaluated as a possibility. For this, the Oasis Montaj software will be applied to perform the 1D and 2D processing with filters that can delimit the edges of the bodies, highlighting their respective features. In association, we will make a composition between filters to better enhance these limits and seek to confirm the possible lateral continuity between the bodies. In addition, with the Sequent Brazil support, the VOXI Modeling tool will be applied to perform the 3D inversion of the bodies and may corroborate the filter results, in order to seek to generate a model for the ACPQ-ACIT.
