Target class: back-arc extension Context triple: [Aegean back-arc extension, instanceOf, back-arc extension]
-
A.
volcanic arc
A volcanic arc is a curved chain of volcanoes that forms above a subducting tectonic plate, typically parallel to an oceanic trench, where magma generated by subduction rises to the surface.
-
B.
oceanic spreading center
An oceanic spreading center is a linear, submarine plate boundary where tectonic plates diverge and new oceanic crust is created by upwelling and solidification of magma.
-
C.
accretionary prism
An accretionary prism is a wedge-shaped mass of sediment and rock scraped off a subducting tectonic plate and accumulated at a convergent plate boundary.
-
D.
subduction-related volcanic arc
A subduction-related volcanic arc is a curved chain of volcanoes that forms above a subducting tectonic plate where descending oceanic lithosphere melts and generates magma that rises to the overriding plate.
-
E.
oceanic fracture zone
An oceanic fracture zone is a linear, seafloor feature formed by past transform fault activity that offsets and segments mid-ocean ridges, marked by steep escarpments and contrasting crustal ages on either side.
- F. None of above. chosen
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.
