Target class: Precambrian rock unit Context triple: [Torridonian Sandstone, instanceOf, Precambrian rock unit]
-
A.
Precambrian crystalline basement
Precambrian crystalline basement is the ancient, typically metamorphic and igneous rock foundation of continental crust that formed before the Phanerozoic Eon and underlies younger sedimentary sequences.
-
B.
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.
-
C.
Paleoproterozoic period
The Paleoproterozoic period was an early era of Earth's history (about 2.5 to 1.6 billion years ago) marked by the rise of atmospheric oxygen, the stabilization of continental cratons, and significant evolutionary advances in early life.
-
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.
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.
- 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.
