Target class: sedimentary rock unit Context triple: [Hell Creek Formation, instanceOf, sedimentary rock unit]
-
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.
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.
-
C.
sedimentary basin
A sedimentary basin is a low-lying region of the Earth's crust where sediments accumulate over long periods, often forming thick sequences of sedimentary rocks.
-
D.
geological basin
A geological basin is a large, low-lying structural depression in the Earth's crust where sediments accumulate over time, often forming significant stratigraphic and resource-bearing sequences.
-
E.
metamorphic rock
A metamorphic rock is a type of rock that has been transformed from an existing rock through heat, pressure, or chemically active fluids, resulting in new mineral structures and textures without the rock melting.
- 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.
