Target class: Precambrian basement Context triple: [Ukrainian Shield region, instanceOf, Precambrian basement]
-
A.
Precambrian crystalline basement
chosen
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.
craton
A craton is an ancient, stable part of the continental lithosphere that has survived geological processes for billions of years, typically forming the core of continents.
-
C.
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.
-
D.
plutonic rock
A plutonic rock is a coarse-grained igneous rock that crystallizes slowly from magma deep within the Earth's crust.
-
E.
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.
- 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.
