Inspire revision 4711 Gyldig

Operationally, the GeologicUnit element is a container used to associate geologic properties with some mapped occurrence (through GeologicFeature.occurrence -> MappedFeature link), or with a geologic unit ControlledConcept in a vocabulary (through the GeologicUnit.classifier ->ControlledConcept link). Conceptually, may represent a body of material in the Earth whose complete and precise extent is inferred to exist (NADM GeologicUnit, Stratigraphic unit in sense of NACSN or Intnl Stratigraphic Code), or a classifier used to characterize parts of the Earth (e.g. lithologic map unit like 'granitic rock' or 'alluvial deposit', surficial units like 'till' or 'old alluvium'). Spatial properties are only available through association with a MappedFeature. Includes both formal units (i.e. formally adopted and named in the official lexicon) and informal units (i.e. named but not promoted to the lexicon) and unnamed units (i.e. recognisable and described and delineable in the field but not otherwise formalised). Will be made Abstract when a complete (enough) set of specialized subtypes is defined.

geologicUnitType A scopped name pointing to a vocabulary defining the type of unit. Logical constraints of definition of unit and valid property cardinalities should be contained in the definition. Use of the CGI Geologic Unit Type vocabulary (eg: something like http://geosciml.org/classifierScheme/CGI/GeologicUnitType/200811) is preferred. GeologicUnitTypeTerm (kodeliste) 1..1
bodyMorphology 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 or process that formed it. CGI_Term (datatype) 1..*
- qualifier A qualifying term (eg; sometimes, common, always) used with term values. ValueQualifierCode (kodeliste) 1..1
- value A byReference attribute, referring to a vocabulary of terms suitable to describe a GeoSciML element. CodeListValue (kodeliste) 1..1
unitComposition Composition-based classification that requires integrating the character of the unit over large area, not applicable at the rock-material/specimen level. Examples: alkalic, subaluminous, peraluminous, I-Type, carbonate, phosphate. CGI_Term (datatype) 1..*

outcropCharacter Describes the nature of outcrops formed by a geologic unit. Examples: bouldery, cliff-forming, ledge-forming, slope-forming, poorly exposed CGI_Term (datatype) 1..*

rank 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 RankTerm (kodeliste) 1..1
unitThickness Typical thickness of the geologic unit. Always reported as a range. If have a single value, the upper and lower limit of range are the same. CGI_NumericRange (datatype) 1..1
- estimatedValue A single measured value chosen on some basis (eg; mean, mode, median, best guess) that is representative for the measurement. Best practice to consider the value and uom attributes of swe:Quantity to be mandatory. Quantity 1..1
GeologicFeature
observationMethod Feature ObservationMethod specifies the approach to acquiring the collection of attribute values that constitute an individual feature instance (e.g. point count, brunton compass on site, air photo interpretation, field observation, hand specimen, laboratory, aerial photography, creative imagination). ObservationMethod is a convenience property that provides a quick and dirty approach to observation metadata when data are reported using a feature view (as opposed to observation view). For a borehole, the GeologicFeature observation method specifies how the geologic properties were determined (eg, visual observation, or standard AzGS logging procedure (described in detail somewhere else)). This property corresponds (loosely) to ISO19115 Lineage. CGI_Term (datatype) 1..*

purpose Specification of the intended purpose/level of abstraction for a given feature or object instance. Scoped name because intention is asserted by author of the data instance. Values are: instance, typicalNorm, definingNorm. DescriptionPurpose (kodeliste) 1..1
