Large areas of the UK offshore are covered, at a scale of 1:250 000. This dataset was originally published between 1984 and 1992, as a series of paper map sheets. This is the first time that the Quaternary Geology 1:250 000 maps have been made available in digital format. Information from the original map sheets have been included in the attribute fields in this dataset, including a lithological description for each formation. Additional data has also been provided where it was deemed to add value. The BGS lexicon code for each formation has been supplied, so users can research any formation of interest. The maximum and minimum age of each formation, in a variety of formats, has also been added. This key information was sourced from Stoker et al (2011). Our understanding of the Quaternary lithostratigraphy is evolving due to the increased data collection associated with renewable energy development. However, no formal update of the regional lithostratigraphic framework has been completed at time of release. This dataset therefore reflects the understanding at the time of original publication. Inaccuracies in the dataset may have since been resolved and the level of uncertainty regarding the age or character of a formation may have changed. Nonetheless, this dataset contains valuable information, and this digital version will help facilitate access to this for users.

These map sheets were published in hard copy format, and subsequently available to view as digital scans via the BGS website. This is the first digital version of this dataset. Information retained from the original map sheets is available in the GIS dataset’s attributes. Additional information has been appended from the Stoker et al (2011) report ‘An overview of the lithostratigraphical framework for the Quaternary deposits on the United Kingdom continental shelf’, NERC research report RR/11/03. This information can be found in the GIS dataset’s attributes and is detailed in the accompanying user guide. Further information regarding the dataset’s generation is described within the User Guide for the dataset (OR/25/049). The GIS dataset and accompanying user guide were compiled by Andrew Dyson and Dayton Dove, with review by Andrew Finlayson.
