The BGS Rock Classification Scheme
Status: stable
definition: The BGS Rock Classification Scheme classifies all types of earth material or other substance that may be recorded in a geological log or section. This is a combined scheme that consists of all concepts from the 3 sub-schemes. The 3 sub-schemes cover different sets of terms (single rocks, composite rocks, dummy rocks) and have different semantics of hierarchical relationship

Geochronology Division
Status: stable
definition: Divisions of geological time from source table DIC_GEOCHRON. The BGS Geochronology Dataset is based on The Geologic Time Scale 2012 by F M Gradstein, J G Ogg, M Schmitz and G Ogg (2012), with additions. The result is a composite geological time scale that will be updated as improved timescales become available.

Description
description: Description may include but is not limited to: an abstract, a table of contents, a graphical representation, or a free-text account of the resource.

Identifier
description: Recommended practice is to identify the resource by means of a string conforming to an identification system. Examples include International Standard Book Number (ISBN), Digital Object Identifier (DOI), and Uniform Resource Name (URN). Persistent identifiers should be provided as HTTP URIs.

Source
description: This property is intended to be used with non-literal values. The described resource may be derived from the related resource in whole or in part. Best practice is to identify the related resource by means of a URI or a string conforming to a formal identification system.

alternative label
definition: An alternative lexical label for a resource.

has broader
definition: Relates a concept to a concept that is more general in meaning.

definition
definition: A statement or formal explanation of the meaning of a concept.

is in scheme
definition: Relates a resource (for example a concept) to a concept scheme in which it is included.

notation
definition: A notation, also known as classification code, is a string of characters such as "T58.5" or "303.4833" used to uniquely identify a concept within the scope of a given concept scheme.

preferred label
definition: The preferred lexical label for a resource, in a given language.

Registry Status Vocabulary
definition: This vocabulary is a re-published and only marginally changed version of the Registry Ontology's (http://epimorphics.com/public/vocabulary/Registry.html) *Status* vocabulary (online in RDF: http://purl.org/linked-data/registry). The only real change to content has been the addition of the term `unstable`. This re-publication has been performed to allow the IRIs of each vocab term (skos:Concept) to resolve to both human-readable and machine-readable forms of content (HTML and RDF), using HTTP content negotiation. Note that just like the original form of this vocabulary, while it is a SKOS vocabulary implemented as a single skos:ConceptScheme, it is also an OWL Ontology and that each *Status* is both a skos:Concept and a reg:Status individual.

Mapplewell Coal
Status: stable
definition: Stratified bedrock. Occurs onshore. Age not entered.
link: /v/vocab/lxcn:NamedRockUnit/NamedRockUnit:S63

Bed
Status: stable
definition: Bed is the smallest formal unit in the hierarchy of sedimentary lithostratigraphical units. Bed names are commonly applied to distinctive units that may be thin and laterally restricted or known only from a borehole or single exposure. Some beds may be fossiliferous or yield dateable material (e.g. a soil, peat or bone bed). Bed status tends to be assigned for units with some palaeogeographical, geochronological or specific lithological significance. This term forms part of the internationally accepted framework for classifying lithostratigraphical units, and has Rank 6 (McMillan, A A, Hamblin, R J O and Merritt, J W. 2011. A lithostratigraphical framework for onshore Quaternary and Neogene (Tertiary) superficial deposits of Great Britain and the Isle of Man. British Geological Survey Research Report, RR/10/03. 343pp.).

Duckmantian Substage
Status: stable
definition: Duckmantian Substage is a substage in the British regional Carboniferous stratigraphic scheme. It is the second of four substages of the Westphalian Stage. It is preceded by the Langsettian Substage and succeeded by the Bolsovian Substage (Geologic Time Scale 2020, fig. 23.5). Replaces: Westphalian Substage B.
