New Data on Late Paleozoic Conglomerates of Wrangel Island and Their Geological Interpretation
Bibliographic record
Abstract
Abstract Conglomerates are widespread in the Paleozoic deposits of Wrangel Island and occur at different stratigraphic levels of the sedimentary cover. Conglomerates of the Central tectonic zone of Wrangel Island previously classified as Carboniferous are represented by two types, which differ in the composition of their components. The conglomerates of the first type have a complex structure. They are dominated by fragments of metamorphic schists and mafic volcanics. The conglomerates of the second type are dominated by rounded fragments of quartz, limestones, and faunal remains. The composition of the conglomerates of the second type is similar to that of intraformational conglomerates from the sections of the Northern tectonic zone. The Guadalupian–Lopingian (Middle–Late Permian) age of these conglomerates was reliably established through the analysis of faunal remains. Thus, conglomerates of the first and second types in the Central zone of Wrangel Island are most likely of different ages, while the later ones (conglomerates of the second type) can be attributed to the Middle–Upper Permian. Two horizons of different-aged conglomerates in the Central zone of Wrangel Island indicate local rearrangements at the beginning of the Pennsylvanian (the Bashkirian Age) and Guadalupian–Lopingian (Middle–Late Permian). Similar rearrangements, accompanied by unconformities, can also be traced in the Permian deposits of the Sverdrup basin of Arctic Canada.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
