Types of slopes in the Transylvanian Depression (Rumania)

Abstract

The Transylvanian Depression is the largest depressionary area inside the Carpathian Mountains. After the basin stage (Upper Cretaceous-Lower Neogene), in parallel with the withdrawal of the Pliocene lake waters and the depletion of erosion levels, sub-aerial modeling began. In this new stage several types of slopes appeared: cuestas, structural surfaces and complex slopes formed in concordance with the geological structure, the Quaternary bioclimatic conditions and the direction of rivers.
