Target class: back-arc basin system Context triple: [Tyrrhenian back-arc basin system, instanceOf, back-arc basin system]
-
A.
back-arc region
chosen
A back-arc region is the tectonic area located on the side of a volcanic arc opposite the subducting plate, often characterized by extension, rifting, and associated magmatism.
-
B.
back-arc extension
Back-arc extension is the process by which the overriding tectonic plate behind a subduction zone is stretched and thinned, often forming a back-arc basin.
-
C.
oceanic basin
An oceanic basin is a large, geologically defined depression on the seafloor that collects ocean water and is bounded by continental margins, mid-ocean ridges, and other submarine features.
-
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.
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.
- 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.
