The BGS Lexicon of Named Rock Units.

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.

Supplemental Information
Includes information imported from earlier databases. Continuously refined and developed to reflect current state of knowledge. The data are incomplete as they are constantly being refined, a flagging system indicates the completeness of individual entries. Detailed definitions only cover land area. A range of Spatial Detail is available. Detailed information available for specific stratotypes. General information for whole UK. There is a degree of logical consistency for entries flagged as 'Formal' or 'Informal'. Other records have varying degrees of logical consistency.
