The BGS Lexicon of Named Rock Units holds definitive and readily accessible information about all allostratigraphical, lithostratigraphical and lithodemic units of member (or equivalent) and higher status that are used, or have been used, on BGS maps and in BGS publications for the UK. It includes information about lesser named units, notably beds (and their equivalents), and some information about names not currently recognised by the BGS or now regarded as obsolete. Some 25% of current Lexicon entries include full definitions, in the BGS context, of formal or informal type. Detail levels in each are broadly comparable, but the informal label is applied if definitions do not yet meet all the criteria of modern stratigraphical procedures. Full Lexicon entries include details of rock unit name, unique computer code, map code, currency, rank, parent unit and parent rank, age, lithology, lower and upper boundaries, thickness, previous or alternative names, geographical extent, stratotypes, occurrence by BGS 1:50 000-scale map (with map code used) and bibliographical references. All entries carry a code describing the level of information held, ranging between full dataset and 'code-only' entries.
