“…6). The same phenomenon has been observed by Olley et al (1998), Colls et al (2001) and Truelsen and Wallinga (2003) in fluvial environments. A complete explanation has not been presented so far, but flocculation of and mud-coating on fine grains and grain-size dependent transport paths have been suggested as possi- ble contributing factors (Fuchs et al, 2005;Truelsen and Wallinga, 2003).…”

“…Generally, in fluvial and glaciofluvial environments, quartz is bleached more rapidly than feldspar (Godfrey-Smith et al, 1988;Fuchs et al, 2005) and the residual dose decreases with transport distance, although input from riverbank erosion or from tributaries may change this pattern (Gemmell, 1988;Stokes et al, 2001). Some variation in dose with grain size has also been observed in fluvial and glaciofluvial deposits (Rhodes and Bailey, 1997;Olley et al, 1998;Colls et al, 2001;Truelsen and Wallinga, 2003;Fuchs et al, 2005).…”

Ripple-laminated sandy deposits at shallow water depths in four rivers on Jameson Land, East Greenland were sampled for optically stimulated luminescence (OSL) dating. Silt-sized grains have significantly higher equivalent doses (~1.1 Gy) than sand grains (~0.1 Gy). This suggests that coarse grain-size fractions are better bleached and more suitable than fine grains for OSL dating of glaciofluvial/fluvial sediments. A sample from a sidebar deposited during the spring flood yielded 1.0 Gy (~500 years) while a subaerial deposit was completely zeroed. The spring flood deposit is considered to be most similar to deglacial conditions and incomplete bleaching of this amount (1 Gy) is generally not a significant source of error for sediments of Pleistocene age. Most samples have rather poor luminescence characteristics and are affected by thermal transfer if preheat temperatures at or above 260°C are used.

“…Low energy conditions have been identified in an number of river channels across the region, for example peat may have continued to form in the Selle (Antoine et al, 2003) and there was reduced flow in the southern Netherlands (Bohncke & Vandenberghe 1991) and north Belgium (Vandenberghe et al, 1984). In the majority of rivers across northwest Europe, however, this period was characterised by meandering behaviour, for example in the Loire in south-central France (Colls et al, 2001), Teleorman in Romania (Howard et al, 2004), Vistula (Starkel, 2002) and Upper Rhine (Dambeck & Thiemeyer, 2002), with some episodes of incision e.g. in the Dneister (Huhmann et al 2003).…”

This paper presents numerical dating from a Middle to Late Pleistocene terrace deposit sequence in the Solent Basin, southern England. The sequence from the western part of the former Solent river system is one of the longest in Britain, with 18 mapped terrace aggradations. A set of 23 optically stimulated luminescence (OSL) dates aim to provide dated tie-points within the lower part of the sequence at five stratotype locations. These dates are replicated at single sites, providing age estimates for fewer members, but increasing the reliability for those members that have been dated. The results provide two reliably dated tie-points within the sequence and suggest that (i) the lowest six terrace aggradations all postdate ca. 275 kyr (MIS 8), (ii) terraces may have aggraded during cold phases within the penultimate interglacial (MIS 7) and (iii) the interglacial deposits at Stone Point whose age has previously been contested are likely to be of Ipswichian (last interglacial, MIS 5e) age. These findings are compared to previous age models in the western Solent basin, with which they agree in part. They may suggest that fluvial activity in the Solent was particularly dynamic during MIS 7.
