Abstract

Very old etchforms of Cretaceous age or older (Pangaean surfaces) are preserved in many parts of the world. Some have been exposed to the elements for very long periods and their persistence poses problems. Moreover, landforms are actively developing within or immediately adjacent to these palaeosurface remnants. Unconsolidated materials, whether occurring as regolith palaeosurfaces or as deposits in valleys and basins, are readily eroded, but coherent rocks are resistant, particularly in well drained situations. A model involving unequal erosion and positive feedback provides optimal conditions for survival
