    Indirect quantitative-qualitative pedologic geomorphic characterization in sub-basin of 7th order of the middle São Francisco watershed – northern Minas Gerais state.
    (2019) Teixeira, Marcílio Baltazar; Martins Júnior, Paulo Pereira; Camargo, Pedro Luiz Teixeira de; Silva, Samuel Tarso da
    The characterization presented in this study aims to identify and map the different types of pedogeomorphic units found in a 7th order, the Pandeiros river basin, in the upper São Francisco River (1st order basin), located in the North of Minas Gerais State. A general panoramic view of the geodiversity is presented, since the Pedogeomorphic Maps allow a visualization of the spatial distribution of the main pedogeomorphic classes, providing important information for various purposes, such as teaching, research and land-use planning. These Maps are relevant specifically for the territorial planning, even without providing data of the local use and occupation because they have strategic information for the understanding and evaluation of the landscape dynamics in region, offering subsidies to the understandings of the processes, phenomena and behaviors of the physical environment related to the different forms of interference of human actions. The Maps also provide support for environmental assessments that have been applied to identify, characterize and monitor trends in environmental aspects.

    Geologic conceptual model of the municipality of Sete Lagoas (MG, Brazil) and the surroundings.
    (2016) Galvão, Paulo Henrique Ferreira; Hirata, Ricardo; Cordeiro, Arnaldo; Barbati, Daniela; Peñaranda, Jorge
    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.
