Target class: stratigraphic sequence Context triple: [Grand Staircase of sedimentary rock layers, instanceOf, stratigraphic sequence]
-
A.
stratigraphic unit
chosen
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.
-
B.
volcanic rock sequence
A volcanic rock sequence is an ordered succession of volcanic rocks, such as lavas, tuffs, and pyroclastic deposits, that records the eruptive history and evolving conditions of a volcanic system over time.
-
C.
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.
-
D.
sedimentary rock
Sedimentary rock is a type of rock formed from the accumulation, compaction, and cementation of mineral and organic particles, often in layered deposits.
-
E.
chronostratigraphic reference point
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.
- 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.
