Target class: coal-bearing sedimentary sequence Context triple: [Waikato coal measures, instanceOf, coal-bearing sedimentary sequence]
-
A.
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.
-
B.
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.
-
C.
coal measures
chosen
Coal measures are thick, stratified sequences of sedimentary rocks—typically including coal seams, shales, sandstones, and mudstones—formed in ancient swampy environments during specific geological periods.
-
D.
coalfield
A coalfield is a geographically defined area containing significant, economically workable deposits of coal, often comprising multiple coal seams and mining operations.
-
E.
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.
- 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.
