Evolução da paisagem e relação solo-relevo : caracterização, gênese e desenvolvimento de depressões na bacia do alto Rio Preto (GO, DF, MG)

Abstract

This paper presents the depressions in the Upper Rio Preto basin. From a total of 177 identified features, most are connected to drain, but is less circular than other identified as isolated. Such features have crisp clusters and indicate be controlled by fault folds from Faixa de Dobramentos Brasília, on comparing the axes with geological alignments. It is important to consider that 90% of depressions dwell on the Group Bambuí, but can not say whether by dissolving its rocks or by dissolving covers.
