Geologic Feature - Abstract - Spatial object type

Definition: A conceptual geological feature that is hypothesized to exist coherently in the world.

Description: This corresponds with a "legend item" from a traditional geologic map. While the bounding coordinates of a Geologic Feature may be described, its shape is not.The implemented Geologic Feature instance acts as the "description package"

Supertype of:


Attributes

Definition: External object identifier of the spatial object.

Multiplicity: 1

Valuetype: Identifier

Definition: The name of the geologic feature.

Description: EXAMPLE: a lithostratigraphic unit, mineral occurrence, or major fault. Not all GeologicFeatures will have names, for example minor faults.

Multiplicity: 1

Stereotypes: voidable

Valuetype: CharacterString


Associated objects - Mandatory

Definition: An identifiable event during which one or more geological processes act to modify geological entities.

Description: A GeologicEvent should have a specified geologic age and process, and may have a specified environment. An example might be a cratonic uplift event during which erosion, sedimentation, and volcanism all take place. A GeologicEvent age can represent an instant in time or an interval of time.

Multiplicity: 1..*

Name of the association: geologic History

Association definition: An association that relates one or more geologic events to a geologic feature to describe their age or geologic history.

INSPIRE Application schema: Geology - [INSPIRE Application schema Geology]


Attributes

Definition: The name of the Geologic Event.

Description: Only major Geologic Events, such as orogenies, are likely to have names.

Multiplicity: 1

Stereotypes: voidable

Valuetype: CharacterString

Definition: The physical setting within which the geologic event takes place.

Description: GeologicEnvironment is construed broadly to include physical settings on the Earth surface specified by climate, tectonics, physiography or geography, and settings in the Earth’s interior specified by pressure, temperature, chemical environment, or tectonics.

Multiplicity: 1

Stereotypes: voidable

Valuetype: EventEnvironmentValue

Definition: The process or processes that occurred during the geologic event.

Description: EXAMPLE: deposition, extrusion, intrusion, cooling.

Multiplicity: 1...*

Stereotypes: voidable

Valuetype: EventProcessValue

Definition: Older boundary of the age of the event.

Description: This is expressed using a geochronologic era defined in a vocabulary of recognised units, such as those of the International Commission on Stratigraphy (ICS) Stratigraphic Chart.

Multiplicity: 1

Stereotypes: voidable

Valuetype: GeochronologicEraValue

Definition: Younger boundary of the age of the event.

Description: This is expressed using a geochronologic era defined in a vocabulary of recognised units, such as those of the International Commission on Stratigraphy (ICS) Stratigraphic Chart.

Multiplicity: 1

Stereotypes: voidable

Valuetype: GeochronologicEraValue


Associated objects - Optional

Definition: A generic thematic classifier to enable the reclassification of Geologic Features with user defined classes appropriate to thematic maps.

Description: This datatype allows Geologic Features to be classified against thematic classes. This provides a generic means of delivering geological thematic map data.

Multiplicity: 0..*

Name of the association: theme Class

Association definition: A thematic classification of the geologic feature.

INSPIRE Data Theme: Geology - [INSPIRE Data Theme Geology]

INSPIRE Application schema: Geology - [INSPIRE Application schema Geology]


Attributes

Definition: The used classification.

Multiplicity: 1

Valuetype: ThematicClassificationValue

Definition: The value of the thematic class.

Description: The thematic class value should be constrained by a codelist of defined terms, but these will commonly be specific to a particular thematic map.

Multiplicity: 1

Valuetype: ThematicClassValue
