1942 A. D. Howard in Jrnl. Geomorphol. 5 11 The term peripediment is suggested for a pediplane which levels an earlier basin fill. If both elements of the pediplane are present, the peripediment is always beyond and peripheral to the pediment.
1970 R. J. Small Study of Landforms ix. 308 The larger and more gently sloping fans may be so extensive as to grade into the alluvial deposits of the peripediment.
1998 Geografia Fisica & Dinamica Quaternaria 21 61/1 The position and evolution of the geomorphological surfaces allows the identification of some main groups:..5. peripediments, rock pediments, locally buried under detritus.
