Sedimentology of the basal glacifluvial talus deposits at Point 3. A) Coarse angular talus at the base of the exposure contains a few well-rounded pebbles (blue arrow). A bed of glacifluvial well-rounded pebbles and cobbles, lying above and to either side of the coarse angular talus, exhibits a chaotic fabric and angular clasts are few. White colouration on clasts is calcite cement; often occurring as menisci on the contact points of pebbles; B) basal section normal to the rock face, the rock face being to the right of the image. Sub-rounded glacifluvial boulders stack against the rock face to the right of the image. Incision into the glacifluvial talus has resulted in a fill of coarse angular scree (centre and bottom left), later filled by a red-coloured sandy matrix. The drape of pebble-sized, angular, cemented scree (overlaying the coarse talus) is visible in the top left corner. Yellow scale bar is 0.8 m; C) close-up of openwork pebble pocket (left centre) surrounded by small cobbles within the glacifluvial talus. Scale bar is 10 × 10 cm and applies to the foreground.

Location of White Scar relative to other prominent limestone escarpments in the vicinity of the Winster and Lyth valleys. Blue bars locate prominent rock barriers. Inset figure shows the location of the study area within the British Isles. Redrawn and modified from Wiltshire (2008) with permission of Carnegie Publishing.

Summary cartoon of talus and scree deposits based on several exposures at White Scar (not to scale). Talus is banked steeply against the foot of the convex cliff face, now buried by scree with the steep exposed cliff face above. A degree of stratification, evident in a fining upward trend in particle size and roundness occurs within some of the talus deposits (but not in all), is shown schematically. Scree prograded over the talus to accumulate on bench 2. Preferential concentration of surface water runoff from the top of the cliff resulted in a thick ribbon of calcified deposits cemented to the cliff face. Seepage-induced calcification extended as ‘spurs’ along layers of permeable openwork scree, the latter lying above less-permeable loess-filled strata. Glacifluvial down-cutting may have occurred locally, truncating the talus, as shown centre-left, before it was buried by scree. Figure © Elizabeth Pickett.

A map of England showing the location of Earsham in Norfolk and the two sets of deposits that form the shallow geology of the site: shallow marine deposit (Crag Group – shaded grey) and glacial deposits (Lowestoft Glacigenic Formation tills and outwash - defined by the blue line which indicates the southern limit of glaciation with the area of concern). The figure also shows the flow trajectories that could be responsible for transporting material to the site. The processes providing the transport are palaeo-rivers, ice flow (glaciers) and ice rafting (icebergs). Taken from the article: 'Boulders, Cobbles and Pebbles in Pleistocene Gravels at Earsham, Norfolk - the scientific value of collecting' by Nick Meade et al.
