Target class: Paleoproterozoic greenstone belt Context triple: [Birimian terranes, instanceOf, Paleoproterozoic greenstone belt]
-
A.
Precambrian crystalline basement
Precambrian crystalline basement is the ancient, typically metamorphic and igneous rock foundation of continental crust that formed before the Phanerozoic Eon and underlies younger sedimentary sequences.
-
B.
batholithic belt
A batholithic belt is a large, elongated region composed of multiple interconnected batholiths—massive bodies of intrusive igneous rock—that formed deep within the Earth's crust and are now exposed over extensive areas, typically along ancient or active continental margins.
-
C.
Paleoproterozoic period
The Paleoproterozoic period was an early era of Earth's history (about 2.5 to 1.6 billion years ago) marked by the rise of atmospheric oxygen, the stabilization of continental cratons, and significant evolutionary advances in early life.
-
D.
mineral belt
chosen
A mineral belt is a geographically elongated region characterized by a high concentration of specific mineral deposits formed by related geological processes.
-
E.
orogenic belt
An orogenic belt is a linear or arcuate region of the Earth's crust where intense deformation, metamorphism, and mountain building have occurred due to plate convergence and collision.
- 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.
