Target class: geological time scale boundary marker Context triple: [GSSP at Enorama Creek, Flinders Ranges, South Australia, instanceOf, geological time scale boundary marker]
-
A.
geologic time scale
The geologic time scale is a chronological framework that organizes Earth's 4.6-billion-year history into eons, eras, periods, epochs, and ages based on major geological and biological events.
-
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.
geologic time interval
A geologic time interval is a span of Earth’s history defined by characteristic rock layers, fossil assemblages, and major geological or biological events, used to organize and correlate geological and paleontological data.
-
D.
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.
-
E.
Devonian boundary
The Devonian boundary is a stratigraphic demarcation that marks the beginning or end of the Devonian Period in Earth's geologic timescale, defined by globally recognized changes in rock layers and fossil assemblages.
- 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.
