comprises large blocks at flatter angles. The deposits are not water-sorted. They are usu-
ally very loose (low bulk density) and just stable at the natural angles. When the deposits
contain 30% or more of fine-grained soil, they are called talus.
Selby (1982) provides a more detailed discussion on the variety of processes of formation
of scree and talus and on the range of fabrics resulting from this. Some talus deposits show
poorly developed soil profiles near the surface or at intervals at depth. These indicate
