Charnockitic rock
type: Concept
Source: Rock Classification Scheme - single rock types sub-scheme
Status: stable
broader: Coarse-grained normal crystalline rock
definition: Rock, charnockitic - A type of coarse-grained normal crystalline rock. The charnockitic suite of rocks is usually characterised by the presence of orthopyroxene (or fayalite plus quartz, though in such assemblages fayalite is invariably altered) and, in many such rocks, perthite, mesoperthite or antiperthite. Primary hydrous minerals are generally absent. They are commonly associated with norites and anorthosites and are linked closely with high-grade metamorphic terrains. Despite being composed largely of feldspar and quartz, charnockitic rocks are generally melanocratic due to very dark feldspar crystals, which also have a characteristically greasy appearance. British Geological Survey Research Report RR/99/06, section 5.1. Examples (root name and qualifier): charnockitic granite, charnockitic monzonite, charnockitic tonalite.

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

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.

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

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

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

definition: Relates a concept to a concept that is more specific in meaning.

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.

Coarse-grained normal crystalline rock
Status: stable
definition: Coarse-grained normal crystalline rock - In the Rock Classification Scheme, a crystalline rock is coarse-grained if its average crystal size is greater than 2 mm. This group corresponds to the plutonic division of the IUGS scheme. British Geological Survey Research Report RR/99/06, section 1.3 and figs. 1, 3 and 9.
