A.
ignimbrite
Ignimbrite is a type of volcanic rock formed from the rapid deposition and welding of hot pyroclastic flows, primarily composed of ash, pumice, and rock fragments.
-
B.
volcanic plug
A volcanic plug is a hardened mass of magma that solidified within a volcanic vent and is later exposed as surrounding softer rock erodes away.
-
C.
ophiolite
An ophiolite is a section of oceanic crust and underlying upper mantle that has been uplifted and exposed above sea level, typically emplaced onto continental crust by tectonic processes.
-
D.
lava dome
A lava dome is a steep-sided, mound-shaped volcanic feature formed by the slow extrusion of highly viscous lava that piles up near a volcanic vent.
-
E.
volcanic rock sequence
A volcanic rock sequence is an ordered succession of volcanic rocks, such as lavas, tuffs, and pyroclastic deposits, that records the eruptive history and evolving conditions of a volcanic system over time.
- 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.
