Class <<FeatureType>> LithostratigraphicUnit (extends LithologicUnit)

Geologic unit that has stratification, allowing specification of thickness and bedding-related properties. Note that while this usage corresponds to the formally definition of 'Lithostratigaphic unit' as defined in the North American Code of Stratigraphic Nomenclature, usage of this element does not denote definition or description of a unit in the sense of the code, only that stratification is present and can be described.

Name Type Bounds From Class Notes
observationMethod CGI_TermValue 1..* GeologicFeature Term(s) that specify the method by which the values for the GeologicFeature were obtained (e.g. point count, brunton compass on site, air photo interpretation, field observation, hand specimen, laboratory, aerial photography, creative imagination...). This corresponds (loosely) to ISO19115 Lineage.

Statement specifies the method that was used to identify the MappedFeature. Examples: .

bodyMorphology CGI_TermValue 0..* GeologicUnit The geometry or form of a GeologicUnit. Examples include: dike (dyke), cone, fan, sheet, etc. Morphology is independent of the substance (EarthMaterial) that composes the GeologicUnit.

compositionCategory CGI_TermValue 0..1 GeologicUnit Term to specify the gross chemical character of geologic unit.
Examples: silicate, carbonate, ferromagnesian, oxide.
Chemical classification terms for igneous rocks also go here.
Examples: alkalic, subaluminous, peraluminous, mafic, felsic, intermediate.

rank ScopedName 0..1 GeologicUnit Term that classifies the geologic unit in a generalization hierarchy from most local/smallest volume to most regional. Scoped name because classification is asserted, not based on observational data.
Examples: group, subgroup, formation, member, bed, intrusion, complex, batholith
