“…Where granitic boulders are present, granular disintegration produces coarse grus at the surface ( Figure 9.5(b)). In this case, some fragments, which were originally very angular in form, may actually show some rounding with time (Al-Farraj, 2008).…”

“…Thomas, Clarke and Pain, 2005;Bailey et al, 2007), there are as yet no detailed studies of the process. Deflationary pavements appear best developed where aeolian sands and gravels occur together (McFadden et al, 1992;Li et al, 2006;Wang et al, 2006;Al-Farraj, 2008). The removal of sand may help in the concentration of gravel to form initial lag deposits.…”

“…The break-up produces small, very angular and uniformly sized clasts that are not subject to further diminution. The highly saline Lake Eyre environment chemically weathers the clast edges, decreasing their angularity over time (Al-Farraj, 2008). …”

“…Pavements and their underlying soils have been widely used as a relative age dating tool owing to the pronounced changes that characterise their development over time (AlFarraj and Harvey, 2000;Al-Farraj, 2008). The differentiation of surfaces into age groups based on pavement development indices has been used to correlate geomorphic surfaces within a region.…”

“…Cooke (1970), for example, noted that the best-developed pavements in Chile occurred on the oldest and highest fluvial terraces. Pavement characteristics have been used to map a number of Quaternary surficial deposits, including alluvial fans (Shlemon, 1978;Christenson and Purcell, 1985;Al-Farraj and Harvey, 2000), stream terraces, shorelines and beach ridges (Sauer, Schellmann and Stahr, 2007;Al-Farraj, 2008), and lava flows (Wells et al, 1985;McFadden, Wells and Jercinovich, 1987;Williams and Zimbelman, 1994). Changes in the chemical composition of varnish and the presence of organic carbon in varnish coating gravel of pavements have been employed to estimate the age of the underlying materials on which the pavement formed (McFadden, Wells and Jercinovich, 1987;Dorn, 1988;Liu and Broecker, 2008).…”

The accumulation of Stone Age lithic artifacts in rock fragment mulches in northern Ethiopia

et al. 2009

Lithic artifacts buried in the soil profile may be transported to the surface during tillage-induced kinetic sieving, differential erosion, or swell-shrink cycles of clays and become part of a rock fragment mulch. Archaeologically, these manifestations are recognized as surface scatters. Although artifacts at the soil surface are difficult to relate to the local stratigraphic context, surface assemblages may provide information on lithic industries and the archaeological significance of sparsely explored regions. Through in situ investigation of surface material in 60 1 ϫ 1 m 2 plots in the Tembien district in the northern Ethiopian highlands, we show that rock fragment mulches can contain a significant number of lithic artifacts and we provide evidence for mid-Pleistocene occupation of a site. Considering that severe rill and gully erosion may be a threat to the archaeological heritage and that well-dated African Middle Stone Age sites are rare, we conclude that the region deserves more attention for archaeological research.

. However, the smallest (length ≤2.5 cm) archaeological fragments are recovered at a much lower rate on this desert pavement surface than expected given comparable data from lithic assemblages in cave and shelter contexts in France. Excavation of archaeological contexts on the Libyan Plateau reveals the loss of small artifact fragments into the subsurface due to aeolian accumulation of silts, whereas geomorphic examination of desert pavement surfaces suggests a potential for relatively isolated bioturbation as a source of lateral and vertical disturbance of desert pavement surfaces over small areas. Archaeologists should be aware of the potential for long-term assemblage stability as well as small artifact burial in surficial desert pavement contexts. C 2013 Wiley Periodicals, Inc.
