Observation Method (Mapped Feature)

"This file contains the CGI Observation Method (Mapped Feature) vocabulary, as defined by the IUGS Commission for Geoscience Information (CGI) Geoscience Terminology Working Group. These are terms that specify how a MappedFeature instance was mapped. MappedFeature ObservationMethod is essentially a metadata snippet indicating how the spatial extent of the mapped feature was determined, and the basis for association of the geometry with some GeologicFeature specification to define a MappedFeature.

Orientation Determination Method

"This scheme specifies concepts used to describe the method used to determine the planar or linear orientation of a GeologicFeature (eg, the dip of a fault), 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. Designed for use in the determinationMethod property in GeoSciML GSML_PlanarOrientation and GSML_LinearOrientation elements."

Particle Aspect Ratio

"This file contains the CGI Particle Aspect Ratio vocabulary, as defined by the IUGS Commission for Geoscience Information (CGI) Geoscience Terminology Working Group. AspectRatio describes the geometry of particles based on the ratios of lengths of long, intermediate and short axes of grains. Equates to sphericity in sedimentary rocks (ie: the degree to which the shape of a particle approximates a sphere). A quantitative specification is based on the ratio of lengths of long, intermediate and short axes of grain shape (Sneed and Folk, 1958; Zingg, 1935).

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.

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."

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."
