A pleistocene frost-heaved dome in palaeozoic limestone at Kingston, Ontario, Canada
Bibliographic record
Abstract
A dome in Palaeozoic limestone at Kingston is 7.5 m in diameter as revealed in a roadcut and about 11 m at its maximum as indicated by ground-penetrating radar. The centre has been displaced 1.5 m upward in the exposure and up to 2.5 m internally in a circular arch. The dome appears to be roughly circular in plan and up-arching of the limestone extends to about 17 m depth. The dome has been eroded to a nearly plane surface by glaciation as indicated by striations on limestone blocks at the surface. Based on similarity of form to features in modern periglacial environments, the dome is proposed to have originated by frost heaving of bedrock before the late Wisconsinan glaciation of southern Ontario. This is the first report of such a feature, and recognition of their occurrence in formerly periglacial regimes should provide a useful tool in palaeoenvironmental reconstruction.

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.
