Particle Shape

"This file contains the CGI Particle Shape vocabulary, as defined by the IUGS Commission for Geoscience Information (CGI) Geoscience Terminology Working Group. The Shape attribute describes, a) the development of crystal faces bounding particles in crystalline compond materials, and b) surface rounding of grains in sedimentary rocks. Roundness is a measure of the sharpness of the edges between surfaces bounding a particle (see Jackson, 1997; Wadell, 1932) and is an indication of the degree of abrasion of a clastic particle.

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.

Processing Activity

"This file contains the CGI Processing Activity vocabulary, as defined by the IUGS Commission for Geoscience Information (CGI) Geoscience Terminology Working Group. The vocabulary defines concepts to categorize processing activities associated with a mining activity. A miningActivity and subsequent processingActivity provide the linkage between a minedMaterial and a mine Product. By extension, this vocabulary includes all concepts in this conceptScheme, as well as concepts in any previous versions of the scheme."

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."

Registry Interchange Format - Collections and Services (Vocabularies)

"The RIF-CS schema is a data interchange format that supports the electronic exchange of collection and service descriptions. It organises information about collections and services into a format used by the Australian National Data Service (ANDS) Collections Registry. More information on the RIF-CS Schema can be found at http://ands.org.au/guides/cpguide/cpgrifcs.html. With assistance from the RIF-CS Advisory Board and user community, ANDS has developed a suggested vocabulary for use with the RIF-CS Schema.

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."
