Fan sediments. (a) Bouldery debris-flow deposits, Zzyzx fans, California. Note the clast fabric - flow was from right
to left. Hammer in centre of photo is for scale. (b) Stratified channel gravels (below) and sheetflood gravels (above) with sand
lenses: Nudos fan, Tabernas, southeast Spain. Hammer for scale. Flow direction was away from the camera. Note that this sequence
approximates to 'Scott'-type sequences of Miall (1978); see also Figure 14.5(a). (c) Bar and swale fan topography: Osbourne Wash
fan, Arizona. (d) Intersection-point seive lobe deposits on a small aggrading fan near Vera, southeast Spain. Note the nose-to-tail
fining and transverse clast alignment; flow direction was towards the camera from right to left. (e) Desert pavement on fan surfaces
at Sinai, Egypt. Note the 'ghost' clasts disintigrating by fracture. Lens cap for scale. (f) Stratified fan deposits, approximating to
the Trollheim type (Miall, 1978; see also Figure 14.5(a)): Cayola fan, Alicante, Spain (d
