Field studies conducted in Dinosaur Park badlands, Alberta, Canada, Chinguacousy badlands, Ontario, Canada and Sestino badlands, Tuscany, Italy, have shown that there are 2 dominant clay-rich lithologies : smectite-rich and smectite-poor mudrocks. Clay minerals have an important role in defining surface and subsurface processes on badland hillslopes. Badland materials were monitored in controlled laboratory conditions during an incremental weathering experiment. It is highlighted that knowing if the material is smectite-rich or smectite-poor can help in prediction of processes and the erosion rates. Precipitation characteristics will determine the rate of weathering on smectite-rich surfaces. Smectite-poor materials appear to be more resistant to change in precipitation characteristics
