Resumo
The study area is located in the state of Minas Gerais, Brazil, among the municipalities of Pedro Leopoldo,
Matozinhos, and Sete Lagoas, with Velhas River as the eastern boundary. It is located in the São Francisco
Craton, where carbonated argillo-arenaceous sediments are emplaced giving origin to the Bambuí Group,
in the São Francisco Basin. Despite the geological knowledge previously developed, the region needs work
on integration and detailing of such information. For this reason, the main objective was to contribute to the
quality of the geologic cartography, the spatial distribution, and the structural framework geometry. Thus,
geologic mapping, aerial photography interpretation, and evaluation of 270 lithologic well profi les were
carried out. It was possible to establish a new geologic perspective of the region by obtaining the detailed
geologic map of the municipality of Sete Lagoas, 14 geologic cross sections, and a geologic conceptual
model. The study showed that the area is within a basin border, presenting a geometry conditioned by
horst and graben system controlled by faulting. This structural feature displaced stratigraphic sequences
positioning them side by side with lithologic sequences with different ages.
