GEOMORPHOLOGICAL STUDY AND SEDIMENT DESCRIPTION OF THE LOWER COURSE OF THE BRUMADO STREAM MICRO BASIN, SANTA RITA DURÃO/MARIANA MG

Abstract

The Quadrilatero Ferrifero is an important metallogenic region constituted by pre-Cambrian lithology that has a great collection of bibliographic materials. The Córrego do Brumado basin is localized on the east edge of the quadrilátero and next to the district of Santa Rita Durão and inserted in the reverse flank named Santa Rita synclinal. This approach focuses on the regional geomorphology with post analysis of the sediments collected on the low stream of the river. With bibliographic research and topographical chart analysis, it was possible recognize the study field and recognize the strategic visitation points. The collected samples were examined through a binocular loupe to obtain details about the aspects of their grains and mineralogy. The local geomorphology was analyzed following the classification of the IBGE geomorphological guide. In the scenario, the geological and geomorphological agents act in the evolution of the basin fluvial geomorphology, how represented in the low stream, where the flooding bank and your low energy contribute to the landscape shaping.
