Synopsis We 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 rep

Synopsis The Late Devensian arctic marine deposits (Errol Clay Formation) at the Gallowflat Claypit between Perth and Dundee are correlated with the type succession at nearby Inchcoonans, but include an expanded basal glaciomarine unit with rhythms i

Synopsis The Bothkennar Gravel Formation ‘buried gravel layer’, which is widespread below the Flandrian carse clays (Claret Formation) of the Forth estuary, is interpreted as having been formed chiefly by ice-rafting of sediment from the shore du

Synopsis At two former oil platform sites (Portavadie and Ardyne) in the Clyde estuary, several metres of very poorly sorted gravelly and cobbly silt and sand of the Portavadie Formation were deposited during the Loch Lomond Stadial. The sediments ar

Increased marine 14C reservoir ages from the surface water of the North Atlantic are documented for the Younger Dryas period. We use terrestrial and marine AMS 14C dates from the time of deposition of the Icelandic Vedde Ash to examine the marine 14C

Synopsis Slope deformation at localities in Glen Roy and Glen Gloy became essentially inactive prior to the formation of glacial lake shorelines (Parallel Roads) that are related to the maximum of Loch Lomond Readvance glaciers (10 500–10 000 BP).

Examination of two radiocarbon-dated vibrocores taken from south of St Kilda at a water depth of about 155 m, a short distance within the maximum position of the Late Devensian (Dimlington Stadial) ice sheet, suggests that the St Kilda Basin became f

It is possible to subdivide the Carse clay deposits above the Bothkennar gravel into bedded, laminated, mottled and weathered faciès. The first is composed of silty clays which retain original sedimentary structures from quiet water tidal deposition
