| http://www.w3.org/2004/02/skos/core#definition | ['Sand with subsidiary gravel and silt and trace boulders. Stratified superficial deposits. Occurs onshore. Formed during the Devensian Stage (Quaternary Period) (.116-.0118 Ma BP).'] |
| http://data.bgs.ac.uk/ref/Lexicon/hasLithologyDescription | ['The two typical lithofacies are beds of very fine- to medium-grained sand, and fine to coarse gravel and boulders with a sandy matrix. The deposit is loose to dense. At Shieldhall (Browne and McMillan, 1989a, Figure 19), west Glasgow, the Member showed a gross upward-fining succession of about 20m thickness. The sands and silts showed flat bedding, ripple-lamination and climbing ripple-lamination, and planar and trough cross-bedding (westward transport). There were indistinct channels filled with massive sand, and two discrete ones up to 2m thick (width not known) containing framework-supported fine to very coarse gravel. Microfaulting was rarely seen and consisted of small reversed faults. There was evidence of soft sediment deformation, in that these deposits and the overlying laminated clays, originally flat-lying, dipped centroclinally into basins at angles up to as much as 80 degrees. This member forms the basal part of the Clyde Clay Formation.'] |
