Landforms and Landscape Evolution of the Equatorial Margin of Northeast Brazil electronic resource An Overview / by Jean-Pierre Peulvast, François Bétard.

Contents:
1 Introduction -- 2 Geological setting: the Borborema Province -- 3 Morphostructural patterns -- 4 Stepped surfaces, palaeolandforms and morphostratigraphy -- 5 Late Cenozoic evolution of landforms -- 6 Conclusion and perspectives.
In: Springer eBooksSummary: More than a simple monograph, the authors present a comprehensive geomorphic overview of a large tropical region where they show how deciphering the long-term landform evolution helps understanding the present set of landscapes and morphodynamic environments. The Equatorial margin of the Brazilian “Nordeste” displays stratigraphic landmarks whose interpretation reveals the age and nature of landforms, leading to a reconstruction of the geomorphic history by the means of combined morphostratigraphic and morphopedological approaches. Beyond the role of differential erosion related to moderate post-oceanic opening uplift, the plain and upland landscape reflects a juxtaposition of landform and soil generations related to a shallow basin inversion, the last stages of which occurred in semi-arid conditions since the Oligocene. These results throw light on old debates on models of long-term landform development in platform areas, and also help evaluating recent models of denudation and burial based on thermochronological methods.
