A period of geologic time, specified by the beginning and ending ages.

temporal_period (O, K: temporal_period(pty_geologic_age_range))

Each pty_geologic_age_range may be a property of one temporal_period.


fossil_taxon (O, K: fossil_taxon(pty_geologic_age_range))

Each pty_geologic_age_range may be a property of one fossil_taxon.


position_on_earth_surface (O, K: position_on_earth_surface(pty_geologic_age_range))

Each pty_geologic_age_range may be a property of one position_on_earth_surface.


other_spatial_object (O, K, I: other_spatial_object(property))

Each pty_geologic_age_range may be a property of one other_spatial_object. Inherited from property.


feature_boundary (O, K: feature_boundary(pty_geologic_age_range))

Each pty_geologic_age_range may be a property of one feature_boundary.


geologic_process (O, K: geologic_process(pty_geologic_age_range))

Each pty_geologic_age_range may be a property of one geologic_process.


rock_fluid_feature (O, K: rock_fluid_feature(pty_geologic_age_range))

Each pty_geologic_age_range may be a property of one rock_fluid_feature.


rock_material (O, K: rock_material(pty_geologic_age_range))

Each pty_geologic_age_range may be a property of one rock_material.


reservoir_fluid_system (O, K: reservoir_fluid_system(pty_geologic_age_range))

Each pty_geologic_age_range may be a property of one reservoir_fluid_system.


activity (O, K, I: activity(process_data))

Defines the activity which created this instance. Each pty_geologic_age_range may be the result of one activity. Inherited from process_data.


earlier_age (O: ndt_time_geologic)

The age of the beginning of a geologic age period. This would correspond to the time most distant from present day.


later_age (O: ndt_time_geologic)

The age of the end of a geologic age period. This corresponds to the age closer to the present day.


preferred_flag (O, I: ndt_boolean) (1047)

The flag is set to True if this instance of property is the preferred value in this data store of this type of property for the object which this property describes. Inherited from property.


data_collection (I, V: SET[0:?] data_collection(collection_content))

Indicates the data collections that include this instance of E and P data. Each pty_geologic_age_range may be a member of one or more data_collection. Inherited from e_and_p_data.


graphical_element (I, V: SET[0:?] graphical_element(depicted_object))

Specifies one or more graphical elements which are depicting this data item. Each pty_geologic_age_range may be depicted by one or more graphical_element. Inherited from e_and_p_data.


process_data_item (I, V: SET[0:?] process_data_item(process_data))

Defines where this data was used by an activity. Each pty_geologic_age_range may be the value for one or more process_data_item. Inherited from process_data.

Local rules:

Uniqueness Constraint
temporal_period, fossil_taxon, position_on_earth_surface, other_spatial_object, feature_boundary, geologic_process, rock_fluid_feature, rock_material, reservoir_fluid_system, activity
[I: property] Mandatory Relationship Set
Each PROPERTY must "be a property of" one object.
Instance Value Constraint
Each PTY GEOLOGIC AGE RANGE must instantiate either or both of earlier_age and later_age.
Supertype path(s):
process_data > property > pty_geologic_age_range.
e_and_p_data > property > pty_geologic_age_range.
