As vertentes na área de S. Miguel-o-Anjo : contributo para o estudo da sua evolução

Abstract

The actual landforms reflect the conjugated activity of the processes connected with the internal and external geodynamics. In the area of «S. Miguel-o-Anjo», in the outskirts of Oporto, one is trying, on the one hand, to demonstrate the importance of the tectonics, particularly the neotectonics, in the genesis and evolution of morphology and on the other hand, to deduce on the morphogenetic processes that have most contributed to the development of those forms along the Quarternary, specially the ones connected with periglacial environment. Morever, the author tryes to emphasize the processes responsable for the present evolution of the slopes, and the changings that occur when actual balance is destroyed, as it happens when florestal fires occur.
