metamorphic facies concepts
This resource defines the concept space for metamorphic facies concepts by extension; it includes all concepts in this conceptScheme, as well as concepts in previous versions of the scheme.

Fettes and Desmons 2007
omphacite-garnet-quartz (no plagioclase, olivine stable with garnet); assemblage for rocks of basaltic composition
eclogite metamorphic facies

hornblende-albite-epidote(-chlorite); assemblage for rocks of basaltic composition
epidote amphibolite metamorphic facies
Concept Definition Task Group of IUGS CGI Interoperability Working Group (http://www.cgi-iugs.org/tech_collaboration/interoperability_working_group.html)
Smulikowski et al., 2003; 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
Concept Definition Task Group of IUGS CGI Interoperability Working Group (http://www.cgi-iugs.org/tech_collaboration/interoperability_working_group.html)
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
Concept Definition Task Group of IUGS CGI Interoperability Working Group (http://www.cgi-iugs.org/tech_collaboration/interoperability_working_group.html)
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
Concept Definition Task Group of IUGS CGI Interoperability Working Group (http://www.cgi-iugs.org/tech_collaboration/interoperability_working_group.html)
this vocabulary
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
Concept Definition Task Group of IUGS CGI Interoperability Working Group (http://www.cgi-iugs.org/tech_collaboration/interoperability_working_group.html)
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
Concept Definition Task Group of IUGS CGI Interoperability Working Group (http://www.cgi-iugs.org/tech_collaboration/interoperability_working_group.html)
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
Concept Definition Task Group of IUGS CGI Interoperability Working Group (http://www.cgi-iugs.org/tech_collaboration/interoperability_working_group.html)
Smulikowski et al. 2003;Fettes and Desmons 2007
Metamorphic facies characterized in rocks of basaltic composition by clinopyroxene-orthopyroxene-plagioclase (olivine stable with plagioclase).
pyroxene hornfels metamorphic facies
Concept Definition Task Group of IUGS CGI Interoperability Working Group (http://www.cgi-iugs.org/tech_collaboration/interoperability_working_group.html)
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
Concept Definition Task Group of IUGS CGI Interoperability Working Group (http://www.cgi-iugs.org/tech_collaboration/interoperability_working_group.html)
Smulikowski et al. 2003; 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
Concept Definition Task Group of IUGS CGI Interoperability Working Group (http://www.cgi-iugs.org/tech_collaboration/interoperability_working_group.html)
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

This file contains the CGI metamorphic facies vocabulary; vocabulary is based on Fettes and Desmons, 2007. Use to populate metamorphic facies property in metamorphic description
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.
2012-02-07 SMR update URI to replace numeric final token with English-language string as in original URN scheme.
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)
