Class <<FeatureType>> GeologicStructure (extends GeologicFeature )

A configuration of matter in the Earth based on describable inhomogeneity, pattern, or fracture in an EarthMaterial.
The identity of a GeologicStructure is independent of the material that is the substrate for the structure.
Properties like "clast-supported", "matrix-supported", and "graded bed" that do not involve orientation are considered kinds of GeologicStructure
because they depend on the configuration of parts of a rock body. Includes sedimentary structures.
The general GeologicRelation is used to associate penetrative GeologicStructures with GeologicUnits.

Attributes

Name Type Bounds From Class Notes
observationMethod Category 1..* GeologicFeature 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.
