Particle Type

"This file contains the CGI Particle type vocabulary, as defined by the IUGS Commission for Geoscience Information (CGI) Geoscience Terminology Working Group. Used to specify particleType in particleTypeDescription associated with a compoundMaterial. Terms to specify the nature of individual particles of each constituent in an aggregation, based mostly on their genesis. Because the constituents are identifiable parts, the part units must have some definition. Examples include clasts, crystals, pore space, material fossil.

Proportion Term

"This file contains the CGI Proportion Term vocabulary, as defined by the IUGS Commission for Geoscience Information (CGI) Geoscience Terminology Working Group. This vocabulary provides terms that may be used to qualitatively express abundance of composition parts in a geologic unit or earth material description. Quantity that specifies the fraction of the geologic unit composed of the compound material. This vocabulary is used for GeologicUnit.GeologicUnitPart.proportion, GeologicUnit.compositionPart.proportion, and for compoundMaterial.ConsituentPart.proportion.

Raw Material Role

"This file contains the CGI Raw Material Role vocabulary, as defined by the IUGS Commission for Geoscience Information (CGI) Geoscience Terminology Working Group. The vocabulary defines concepts for categorizing raw material relationships with Earth Resource occurrences. By extension, this vocabulary includes all concepts in this conceptScheme, as well as concepts in any previous versions of the scheme."

Reserve Assessment Category

"This file contains the CGI Reserve Assessment Category vocabulary, as defined by the IUGS Commission for Geoscience Information (CGI) Geoscience Terminology Working Group. The vocabulary defines concepts for classifying reserve types associated with Earth resource occurrences. By extension, this vocabulary includes all concepts in this conceptScheme, as well as concepts in any previous versions of the scheme."

Resource Assessment Category

"This file contains the CGI Resource Assessment Category vocabulary, as defined by the IUGS Commission for Geoscience Information (CGI) Geoscience Terminology Working Group. The vocabulary defines concepts to describe methods and quality of resource assessment within an Earth Resource. By extension, this vocabulary includes all concepts in this conceptScheme, as well as concepts in any previous versions of the scheme."

Simple Lithology

"This scheme specifies the concept space for Simple Lithology concepts, as defined by the IUGS Commission for Geoscience Information (CGI) Geoscience Terminology Working Group. By extension, it includes all concepts in this conceptScheme, as well as concepts in any previous versions of the scheme. This vocabulary is not designed to be a comprehensive list of all lithology terms."

UNFC Code

"This file contains the CGI UNFC Code vocabulary, as defined by the IUGS Commission for Geoscience Information (CGI) Geoscience Terminology Working Group. The vocabulary defines concepts for the categorisation of mineral reserves and resources according to the UN Framework Classification (2009). By extension, this vocabulary includes all concepts in this conceptScheme, as well as concepts in any previous versions of the scheme."
