SUMMARYThe history of Late Weichselian and Flandrian vegetation in south-west Scotland has been studied by examining sites ranging from near sea-level up to about 1500 ft O.D. (c. 500 m). Pollen was scarce or absent in Lower Dryas sediments, but the relatively high counts in Allerod sediments implied that an open herbaceous vegetation was established before this time. Throughout the Late Weichselian the vegetation was an herbaceous one which became more stable and denser during the Allerod, but was much reduced during Upper Dryas time. Early Flandrian vegetation remained open and the spread of birch woodland was delayed for some time. Once established the birch forests remained dominant or co-dominant for a long period and were never completely replaced by mixed-oak forest. Because of the differences in vegetation development it was difficult to correlate significant changes in the pollen curves with the standard British system of pollen zones. For this reason an attempt has been made to devise a system of zones appropriate for Scotland which bears comparison with the presently accepted scheme. Apparent breaks in sedimentation at Bigholm Burn and Culhorn Mains, only revealed by pollen analysis, are treated as local phenomena, the causes of which had no effect upon the character of the regional vegetation. Radiocarbon assay of samples from Bigholm Burn show that the ages of Allerod sediments are consistent with those from other parts of Britain, but early and mid-Flandrian dates are considerably younger than their biostratigraphical equivalents elsewhere. Until more dates are available from the region this apparent anomaly is regarded as being an effect of local factors influencing forest development and sedimentation. Although the distribution of sites about the Southern Uplands implies that glaciers were restricted to higher altitudes the present study does not add significantly to our knowledge of the extent of glaciation in this region during the Late Weichselian.

“…The area is noteworthy for its streamlined landforms (mainly drumlins), the orientation of many conforming with the derivation of the upper till from the NE (Charlesworth, 1926;Salt and Evans, 2004). However, the last iceflow was towards the SSE along Loch Ryan and into the upper part of Luce Bay (Figure 1; Salt, 2001;Salt and Evans, 2004).…”

“…At glacial maximum it has been argued that the peninsula was overridden by the main Scottish Ice Sheet, and during deglaciation a series of ice streams crossed the area, until final disappearance of the ice sheet toward the end of the Lateglacial Period (Charlesworth, 1926, Kerr, 1982, McCabe et al, 1998, Salt & Evans, 2004, Bradwell et al, 2008. Three decades ago, it was suggested that high-arctic marine deposits formerly seen in two claypits in SW Scotland were possible representatives of the high-arctic Errol Clay Formation of eastern Scotland, and were thus of Devensian lateglacial age (Peacock, 1975).…”

“…However, the last iceflow was towards the SSE along Loch Ryan and into the upper part of Luce Bay (Figure 1; Salt, 2001;Salt and Evans, 2004). Charlesworth (1926) suggested that kame moraines forming a belt south of Stranraer (his Stranraer Moraine) resulted from a readvance of ice from the north, but the kames, eskers, and dead-ice topography indicate stagnant rather than active ice (Sutherland, 1993). However, the idea that there was a readvance has not been entirely rejected (Salt and Evans, 2004).…”

SynopsisWe present new interpretations of Digital Elevation Model (DEM) data and marine fossils collected from three sites on the Rhins of Galloway which, contrary to recent proposals, suggest that the landforms and deposits of the region do not represent evidence for a readvance during the Lateglacial Period. Rather we suggest that the higharctic fauna found in the region are representative of an earlier, colder part of a Middle Devensian ice-free interval. The predominantly streamlined topography, and distinct lack of identifiable discrete moraine limits argues for only minor, local glacial advances, in combination with widespread rapid retreat across the peninsula at the end of the Lateglacial.

The Carstairs Kames have been the subject of debate for over 150 yr. A synthesis of previous work, along with new sedimentological data, is used to reappraise this classic British esker locality. Three morphological elements are recognised: (i) large, sinuous and anastomosing ridges; (ii) large, irregular, linear mounds; and (iii) small, low and irregular mounds. The main ridge system is composed of a core of boulder gravel with sand/pebble gravel above and adjacent to the core. The large, linear mounds contain a varied facies range which include: glaciolacustrine sediments (deltaic sequences, laminites and dropstones); debris flows; and glaciofluvial channel systems. All the deposits, both in the main ridges and in the adjacent linear mounds, contain syn‐and post‐depositional subsidence structures, including normal faults, synclinal folds and growth faults. A range of potential origins for these landforms is reviewed and it is suggested that glaciofluvial sedimentation in a supraglacial environment, controlled by a topography of ice‐cored ridges, is the most appropriate depositional model. © 1997 John Wiley & Sons, Ltd.
