Description :
This paper describes how mass movement is dissecting a relict alluvial fan at the margin of the Sele Valley graben. Rock mass structure and neotectonics are treated here, not as controls upon fan sedimentation, but as a fundamental cause of the instability of inactive fan sediments. The AA. use detailed geological and geomorphological mapping and interpretation to show how faulting and stratigraphic variations have created slump features, subsidence zones, scarpettes and cemented colluvium aprons in the vicinity of the fan.
