Generic_Geologic_Time_Unit c
IRI |
https://w3id.org/gso/1.0/geology/Generic_Geologic_Time_Unit
|
---|---|
Description | A generic geologic time interval (e.g. Jurassic) having specific manifestations (e.g. Jurassic 2017). The specific manifestations are its essential parts, while the generic interval is the whole. These time intervals are largely defined by their position between other intervals, without necessarily specifying their bounding time instants. Generic geologic time intervals such as Jurassic are not types (classes) for practical and ontological reasons. Practically, it would imply a cumbersome and complex multi-level ontology: time ranks such as Period would be metatypes (following biological ranks such as Species; Carvalho & Almeida 2016) that instantiate time intervals such as Jurassic, that in turn instantiate Jurassic 2017. It would also be more complex to specify e.g. Jurassic (a type) as the age of a formation (an individual), due to non-instantiation relation between an individual and a type. Ontologically, it would imply Jurassic is not a time span, which is contrary to stratigraphic codes that consider Jurassic (as a geochronologic unit) to be an actual chunk of time: "...units of geologic time... represent [a] span of time ..." (NACSM 2005) and "Geochronologic units are units of time..." (Murphy & Salvador 1998). For these reasons, generic geologic time intervals, such as Jurassic, are considered in GSO to be individuals with essential parts, such as Jurassic 2017. However, it remains somewhat of an open question whether this characterization is indeed best. |

Geologic Event c
IRI |
https://w3id.org/gso/1.0/geology/Geologic_Event
|
---|---|
Description | When something happens, events are the ‘what’ of the happening, and processes are the ‘how’. E.g. the Trans-Hudson Orogeny (event) caused by a subduction (process). The relation between events and processes is constitution: events are constituted by processes, and processes constitute events. Geologic processes and events have at least one geologic endurant as participant, i.e. a happening cannot occur unless it happens to something. Events can only have events as parts. |

---|---|
Description | A temporal feature that is the boundary between two Geologic time Intervals. Is generically dependent on a date, so can possibly change or could possibly have been a different date - e.g. the end of the Anthropocene is the current moment, which changes with each moment, and the start of the Anthropocene could have been a different time if Erath history was different. |

Description | A temporal coordinate value, located either by a point position (with uncertainty) on a time line, specified by a numeric coordinate (generally MYPB, but definitions of 'present' vary). Can be a GSSA if the numeric time coordinate is arbitrarily assigned. Probably should specify a Temporal Reference System used to assign coordinate values. |

There are 3 primary types of geologic time intervals - these are not comprehensive (i.e. there could be additional types): generic (e.g. Jurassic), specific (e.g. Jurassic 2017), and time scale (ISC 2017). |

Geologic Time Scale c
IRI |
https://w3id.org/gso/1.0/geology/Geologic_Time_Scale
|
---|---|
Description | A time scale is a geologic time inteval in GSO - it is a rock-dependent span of time that is internally divided into other rock-dependent spans of time following a certain topology (after Simon & Cox, 2010). Rock-dependence implies it is intrinsically tied to a specific rock object (e.g. the Earth's rock mass) and internal subdivision implies it is a collection of other geologic time intervals. Moreoever, any change to the parts of the collection results in a different time scale - this implies geologic time intervals cannot be essential parts of a time scale without being static parts (see Brodaric et al, 2019 for types of parts). Time scales are also not part of other time scales, nor part of specific or generic geologic time intervals. This is primarily to maintain internal temporal topology, though this constraint could be relaxed if use-cases warrant. Aligned generally with (Cox and Richard, 2010). |
