Sedimentary facies and progradational style of a Pleistocene talus-slope succession, Northern Calcareous Alps, Austria

The change from alluvial-fan deposition along the toe of initially high cliffs towards climbing onlap and progradation of talus slopes occurred when a slope segment dipping with the mean angle of residual shear of talus material had formed at the apex of the fan. Because the free cliff face supplying talus deposition diminishes with time, the progradation potential of talus slopes is inherently limited.
