The watersheds captures: morphotectonics evidence in the contact of the plateau with the dissected relief of Tijuco river basin (MG)

Abstract

The paleogeographic origin of the survey area includes the occurrence of volcanic flows that gave rise to the basalts of the Serra Geral Formation, rock found at the base of the main streams of the region. Over them, occur the sandstones of Bauru Group. This group is represented in this area by: i) Marilia Formation sandstones; ii) Adamantina Formation; iii) Uberaba Formation. The search area corresponds to the basins of streams Douradinho, Panga and Estiva, tributaries of the Tijuco river (MG), located in the West of the Triângulo Mineiro in the contact of the dissecated plateau with the
Tijuco river (MG). In this compartment are found intense gullies aligned with ruputures in the slopes, and also with the
base level lowering.
