Target class: magmatic arc Context triple: [Cordilleran magmatic arc, instanceOf, magmatic arc]
-
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.
subduction-related volcanic arc
chosen
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.
-
C.
mantle plume
A mantle plume is a localized, buoyant upwelling of abnormally hot rock rising from deep within the Earth's mantle toward the surface, often producing volcanic hotspots and large igneous provinces.
-
D.
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.
-
E.
intra-plate volcanic province
An intra-plate volcanic province is a broad region of volcanic activity that occurs within a tectonic plate, away from plate boundaries, typically associated with mantle plumes or hotspots.
- 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.
