Abstract

This work deals with an integrated geomorphological and chemical–physical study of "calanchi" landforms in site (Caulonia) of SE Calabria (southern Italy), developed on of Late Pliocene–Quaternary clay deposits. A comparison has been made among the physical, chemical and mineralogical features of calanchi materials sampled after a rainy period precipitation with those sampled after relatively dry period and in different topographic settings (opposite flanks of a catchment exhibiting different steepness and lengths i.e. W- to NW-facing and E- to NE-facing slopes). Using a multivariate statistic approach – which adopts the principal component analysis (PCA) method to extract factors – it has been possible to make a hypothesis of the main processes responsible for dynamic evolution of the study area. The rainfall quantity coupled with topography has to be considered as the main control factor inducing changes in the physical–chemical–mineralogical parameters.
