Metamorphic Facies
This file contains the CGI Metamorphic Facies vocabulary, as defined by the IUGS Commission for Geoscience Information (CGI) Geoscience Terminology Working Group. The vocabulary is based on Fettes and Desmons (eds.), 2007, METAMORPHIC ROCKS: A CLASSIFICATION AND GLOSSARY OF TERMS - Recommendations of the International Union of Geological Sciences Subcommission on the Systematics of Metamorphic Rocks. Used to populate metamorphic facies property in metamorphic descriptions. By extension, this vocabulary includes all concepts in this conceptScheme, as well as concepts in any previous versions of the scheme.
This file contains the 2016 SKOS-RDF version of the CGI Metamorphic Facies vocabulary. Compilation and review in MS Excel spreadsheet, converted to MS Excel for SKOS generation using SKOS_for_GA_from_XLS_2016.03.xslt
2010-02-11 Add narrower relationship links by adding skos:narrower link in Protege, defining skos:narrower as inverse of skos:broader, calculating with Pellet reasoner to add inferred axioms, and using 'file/Export inferred axioms as ontology' in Protege.
2010-11-28 SMR Replace URN identifiers with http URI identifiers according to CGI URI scheme (see https://www.seegrid.csiro.au/wiki/bin/view/CGIModel/PersistentIdentifiersInGeoSciMLServices)
2012-02-07 SMR update URI to replace numeric final token with English-language string as in original URN scheme.
2012-02-27 SMR add skos:exactMatch triples associating URIs with number token URI in 201012 version.
2012-11-24 SMR Update to 201211 version; add collection entity, check all pref labels are lower case, remove owl:NamedIndividual and Owl:Thing rdf:types.
2016-11-21 OLR regenerate SKOS-RDF file as part of migration to new vocabulary server. Minor corrections to hierarchy from the previous 2012 version.

Metamorphic facies characterized in rocks of basaltic composition by hornblende-plagioclase (plagioclase more calcic than An17).
amphibolite metamorphic facies
Smulikowski et al. 2003; Fettes and Desmons, 2007
Omphacite-garnet-quartz (no plagioclase, olivine stable with garnet), assemblage for rocks of basaltic composition
eclogite metamorphic facies
Fettes and Desmons, 2007
Hornblende-albite-epidote(-chlorite), assemblage for rocks of basaltic composition
epidote amphibolite metamorphic facies
Fettes and Desmons, 2007
Metamorphic facies characterized in rocks of basaltic composition by glaucophane-epidote (-garnet), glaucophane-lawsonite, or glaucophane-lawsonite-jadeite.
glaucophane schist facies
Smulikowski et al. 2003; Fettes and Desmons, 2007
Metamorphic facies characterized in rocks of basaltic composition by the mineral assemblage clinopyroxene-orthopyroxene-plagioclase (olivine not stable with plagioclase or with garnet), or especially high-temperature varieties or polymorphs of minerals (e
granulite facies
Smulikowski et al. 2003; Fettes and Desmons, 2007
Metamorphic facies characterized in rocks of basaltic composition by actinolite-albite-epidote-chlorite (an epidote group mineral is the diagnostic Ca-Al silicate rather than prehnite or pumpellyite).
greenschist metamorphic facies
Smulikowski et al. 2003; Fettes and Desmons, 2007
Metamorphosed, but facies not specified in more detail. For use in normative description to indicate that any metamorphic facies value is valid.
metamorphic facies not specified
this vocabulary
For use in instance descriptions to indicate that no data are available to constrain metamorphic facies. May be metamorphosed or non-metamorphosed.
metamorphic facies unknown
this vocabulary
Corresponds to non-metamorphosed condition, since metamorphic facies classification is based on mineral assemblages, absence of metamorphic minerals means that the classification does not apply.
no metamorphic minerals
this vocabulary
Metamorphic facies characterized in rocks of basaltic composition by clinopyroxene-orthopyroxene-plagioclase (olivine stable with plagioclase).
pyroxene hornfels metamorphic facies
Smulikowski et al. 2003; Fettes and Desmons, 2007
distinguished from the pyroxene hornfels facies by the occurrence of especially high-temperature varieties and polymorphs of minerals (eg. pigeonite, K-rich labradorite), assemblage for rocks of basaltic composition
sanidinite metamorphic facies
Fettes and Desmons, 2007
Metamorphic facies characterized in rocks of basaltic composition by prehnite-pumpellyite, pumpellyite-actinolite, prehnite-actinolite (prehnite and pumpellyite are the diagnostic Ca-Al silicates rather than minerals of the epidote or zeolite groups).
subgreenschist metamorphic facies
Smulikowski et al. 2003; Fettes and Desmons, 2007
Metamorphic facies characterized in rocks of basaltic composition by zeolite minerals such as laumontite and heulandites (in place of other Ca-Al silicates such as prehnite, pumpellyite and epidote).
zeolite metamorphic facies
Smulikowski et al. 2003; Fettes and Desmons, 2007
