This dataset shows the distribution of Middle Jurassic, Upper Jurassic and Lower Cretaceous lithostratigraphic (UK Offshore Operators Association - UKOOA) units within the UK North Sea graben. The data are based on a subset of released exploration and appraisal wells from within the UK North Sea graben areas. The well data are concentrated in the areas overlying the deep sedimentary basins of the Viking Graben, Central Graben and the Moray Firth Basin, with fewer wells over the adjacent platforms. The UKOOA lithostratigraphic classification has been applied consistently.

A coherent series of flat-file geotechnical datasets generated during the applied geology mapping of Exeter, Deeside, Coventry, Nottingham, Bath, Castleford/Pontefract, and the Black Country, and mapping of the Thame 1:50k sheet. For each of these projects, data were abstracted from the available site investigations within the mapping area. The structure of the datasets is limited, in that all geological and geotechnical data are attributed to 'samples' at discrete depths. The datasets include the more common geotechnical parameters, although some are entered as only class intervals, rather than in detail. All the datasets are held as paper coding sheets, with minor variations between projects. Most were digitised in Smartware and/or Statgraphics software and may not be readily accessible.

The Lexicon of Named Rock Units provides definitions of lithostratigraphic, lithodemic, and litho-morpho-genetic geological units of the United Kingdom and its associated continental shelf. The Lexicon focuses mainly on units of Member, Formation, Group and higher rank (and equivalents) but it also includes information on some units of lesser rank, notably economically important coal seams and laterally extensive marine bands. It includes superficial and bedrock units. It includes synonyms and other names not currently recognised by the BGS or regarded as obsolete. Full Lexicon entries include geological unit name, a persistent unique identifier, map code, currency, rank, parent unit and rank, age, lithology, definitions of boundaries, thickness, previous and alternative names, geographical extent, type localities, and bibliographical references.
