Target class: stratigraphic boundary marker Context triple: [Global Boundary Stratotype Section and Point, instanceOf, stratigraphic boundary marker]
-
A.
chronostratigraphic reference point
chosen
A chronostratigraphic reference point is a precisely defined boundary in geological time, often marked by a Global Boundary Stratotype Section and Point (GSSP), used to correlate and standardize rock layers and time intervals worldwide.
-
B.
geological boundary
A geological boundary is a conceptual division in the Earth's crust that separates distinct rock units, layers, or geological features based on differences in age, composition, structure, or formation history.
-
C.
stratigraphic unit
A stratigraphic unit is a volume of rock or sediment defined and distinguished from adjacent material by its recognizable and mappable physical, chemical, or paleontological characteristics and its position in the geological record.
-
D.
marine biogeographic boundary
A marine biogeographic boundary is a transition zone in the ocean where distinct marine species assemblages and ecological communities change markedly due to shifts in environmental conditions such as temperature, currents, or salinity.
-
E.
chronostratigraphic chart
A chronostratigraphic chart is a diagram that organizes rock layers and geological events in chronological order to illustrate the relative timing and duration of Earth’s stratigraphic units.
- F. None of above.
Provenance (1 batch)
The batch behind each pipeline step, in order, with when it ran. Timestamps are batch-level — stages were processed in waves, so the object chain (NER → NED1 → NEDg → NED2) reads in order, but predicate / elicitation batches can sit in a different wave.
