Ice-marginal depositional responses to readvance episodes in the Late Devensian deglaciation of the Isle of Man

Ice sheet advance, dynamics, and decay configurations: evidence from west central Scotland

“…2,5,14) shows location of study area in west central Scotland. Proposed former glacier ice limits and ages from Sissons (1967b), Dawson (1982, Rose et al (1988), Peacock and Merritt (1997), McCabe et al (1998McCabe et al ( , 2003, Thomas et al (2004), Ballantyne (2007), and McCabe (2008). Key place names are shown.…”

The palaeoglaciology of the central sector of the British and Irish Ice Sheet: reconciling glacial geomorphology and preliminary ice sheet modelling

“…Scourse (1991), Scourse and Furze (2001), Hiemstra et al (2005) and Ó Cofaigh and Evans (2007) provide evidence that the BIIS reached the Scilly Isles and the south coast of Ireland after 20.2 14 C ka BP (23.9 cal ka BP). To the north, McCabe andClark (1998, 2003) and McCabe et al ( , 2005McCabe et al ( , 2007 (Thomas et al, 2004). Specifically, terrestrial plant remains from the basal layers of kettle basins date to the beginning of the late glacial interstadial at 14.0-14.4 and 14.2-15.0 cal.…”

A polyphase glacitectonic model for ice-marginal retreat and terminal moraine development: the Middle Pleistocene British Ice Sheet, northern Norfolk, UK

“…Previously, they have been considered as providing a visible record of a maximum extent of glacier advance, although many now consider them to provide a more dynamic record of glacier retreat (e.g. Thomas, 1984;Thomas et al, 2004;Thomas and Chiverrell, 2007;Lüthgens and Böse, 2011; Clark et al, 2012).…”

“…Previously, they have been considered as providing a visible record of a maximum extent of glacier advance, although many now consider them to provide a more dynamic record of glacier retreat (e.g. Thomas, 1984;Thomas et al, 2004;Thomas and Chiverrell, 2007;Lüthgens and Böse, 2011; Clark et al, 2012).The formation of terminal moraines typically involves the complex interplay between ice-marginal to sub-marginal sedimentation and glacitectonics; the latter including proglacial and sub-marginal bulldozing, thrusting and squeezing (Benn and Evans, 2010) as a result of either 'thin-skinned glacitectonics' (Croot, 1987;Banham, 1988b) or 'gravity spreading' as a consequence of loading of the underlying sediment pile (Rotnicki, 1976; Van der Wateren, 1985; Aber et al, 1989). The morphology and internal structural architecture of terminal moraines, in particular the superimposition of different subglacial, sub-marginal and proglacial features, can provide detailed insights into larger-scale patterns of ice dynamics such as phases of ice advance, still-stand and retreat (Krüger, 1993;Van der Wateren, 1995, 2005Thomas and Chiverrell, 2007).…”
