Historical development of a litho- and biostratigraphic framework for onshore Cretaceous-Paleocene deposits along western Baffin Bay
Bibliographic record
Abstract
Cretaceous-Paleogene strata along the eastern coast of Baffin Island, on Bylot Island, and on associated islands north of Cape Dyer, have been known since the early days of exploration of Baffin Bay in the mid-nineteenth century. Studies of these strata in the 1970s-1990s established their clastic nature and revealed details of their stratigraphy, ages, and depositional settings. Onshore strata in the Cape Dyer area accumulated in close association with volcanic deposits related to late-stage rifting in the Late Cretaceous to Early Paleocene that eventually formed Baffin Bay. In contrast, deposits in more northerly areas, such as the Eclipse and North Bylot troughs on Bylot Island, exhibit similar clastic rocks, but lack conspicuous volcanic strata, and have been associated with either the Sverdrup Basin or the Baffin Bay rift. The litho- and biostratigraphy of these deposits are summarized and discussed in terms of differing and contrasting stratigraphic interpretations, age assignments, and depositional environments.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
