Target class: back-arc spreading ridge Context triple: [Central Lau Spreading Center, instanceOf, back-arc spreading ridge]
-
A.
oceanic spreading center
chosen
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.
-
B.
back-arc region
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.
-
C.
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.
-
D.
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.
-
E.
continental rift
A continental rift is a linear zone where a continent is being pulled apart by tectonic forces, causing the crust to thin, fracture, and often form rift valleys and volcanic activity.
- 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.
