Integrated ichnology, sedimentology and stratigraphy of the lower cretaceous Grand Rapids formation and equivalents, east-central Alberta
Bibliographic record
Abstract
Uppermost parasequences of the Grand Rapids Formation and Upper Mannville Group record progradation of open-coast wave/storm-dominated deltas in the west, passing eastward into brackish-water bay-head deltas. Distributary channel deposits occur in close proximity to both settings. Stratigraphic cross-sections indicate that autocyclic delta lobe switching occurred in both delta types. Open-coast deltas contain low-diversity trace fossil suites consisting of slightly more robust ichnogenera, most of whom reflect opportunistic colonization of storm beds. Ichnogenera typical of more marine conditions are sporadically distributed, indicating that environments were not as persistently salinity stressed as in the east. Bay-head deltas in brackish-water settings display the lowest trace fossil diversities and pronounced size reductions. Facies lack ichnogenera associated with more marine conditions. Brackish-bay deposits are the most intensely burrowed, attesting to low deposition rates. Ichnological diversities are slightly greater than in bay-head delta deposits, reflecting less marked salinity fluctuations in persistently brackish-water conditions.

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.
