Target class: Proterozoic tectonic feature Context triple: [Midcontinent Rift System, instanceOf, Proterozoic tectonic feature]
-
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.
Mesozoic geological feature
A Mesozoic geological feature is a rock formation, structure, or landform that originated or was significantly shaped during the Mesozoic Era (about 252 to 66 million years ago), often preserving evidence of ancient environments and life such as dinosaurs and early mammals.
-
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.
Neoproterozoic period
The Neoproterozoic period is the final era of the Proterozoic Eon, spanning roughly 1,000 to 541 million years ago, marked by major climatic events such as global glaciations ("Snowball Earth") and the emergence of complex multicellular life.
-
E.
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.
- 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.
