Target class: sedimentary rock sequence Context triple: [Old Red Sandstone, instanceOf, sedimentary rock 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.
subduction zone
A subduction zone is a tectonic boundary where one lithospheric plate sinks beneath another into the mantle, generating intense seismic activity, volcanism, and mountain building.
-
C.
craton
A craton is an ancient, stable part of the continental lithosphere that has survived geological processes for billions of years, typically forming the core of continents.
-
D.
oceanic trench
An oceanic trench is a long, narrow, and extremely deep depression in the ocean floor, typically formed at convergent plate boundaries where one tectonic plate subducts beneath another.
-
E.
geologist
A geologist is a scientist who studies the Earth’s materials, processes, and history to understand its structure, evolution, and natural resources.
- 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.
