Abstract

Abstract In the central portion of Brazil, there are extensive and continuous flat surface plateaus, which are presented in a staggered way, separated by embedded fluvial valleys, among which the Uberlândia-Uberaba plateau stands out in the region of Triângulo Mineiro - MG. Considering the aforementioned, geomorphological features such as veredas and summit depressions populated by murundus, commonly associated to the drainage network in tabular relief, are considered here as key environments for paleoenvironmental interpretation. To characterize and understand the formation processes of these environments and their evolution in the landscape, morphometric indexes, topographic profiles and evolutionary models of landscape were elaborated, presenting a general panorama and demonstrating the importance of geomorphological elements and landscapes from Paleogene planation surfaces to the Holocene climatic pulses.
