Sedimentology, stratigraphy, and clast biostratigraphy of Cretaceous and Tertiary strata, northeastern Ellesmere Island, Nunavut
Bibliographic record
Abstract
The Eureka Sound Group clastic deposits on northeastern Ellesmere Island make up over 3 km of strata of Late Paleocene-Early Eocene age and were deposited in braidplain to alluvial fan and alluvial plain environments. The new Pavy Formation is the oldest unit, and consists of coarse-grained, volcanic-rich, channel-deposit sandstone displaying abundant, decimetre-scale trough-crossbedding. Boulder polymictic orthoconglomerate typifi es the alluvial fan deposits of the Cape Lawrence Formation and grades into the fi ne-grained calcarenite of the Cape Back Formation, deposited in a fl oodplain environment. The mineralogy refl ects the changing nature of the tectonic regime resulting from the movements between Canada and Greenland during the Late Paleocene. Clasts in the conglomerate yield faunas rang- ing in age from latest Cambrian to Early Devonian. Identifi ed faunas and conodont colour alteration indices are highly variable and do not indicate a simple unroofi ng history.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.
How this classification was reachedexpand
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.
