Abstract

This study has been carried out on three pairs of clayey-silt slopes, which are examples of typical badlands near Aliano (Southern Italy). These show features of erosion which are common to SE-exposed clayey-silt rocks outcropping in the same area. After mineralogical, geochemical and grain size analyses these slopes were compared with the SE-exposed adjacent ones, having however a different erosive action, and a partially-vegetated covering was found. Pedological analyses show a clear development of soil horizons where the slope is rich in organic matter, and this is wholly consistent with the presence of vegetation. This study therefore shows that the erosion mechanism involves morphological and geographic exposure, climatic elements as well as grain size, mineralogy, chemistry and the exchange processes of soil
