Late Wisconsinan stratigraphy and chronology at Highlands, southern St. George’s Bay, southwest Newfoundland
Bibliographic record
Abstract
This paper provides detailed sedimentological and chronological data of coastal exposures at Highlands in southern St. George’s Bay, southwest Newfoundland. The Highlands section shows a coarsening upward sequence from mud to sand and gravel, and diamicton, and represents an ice-distal to ice-proximal glaciomarine environment, where sediment was introduced via a subglacial meltwater jet and deposited by under#ow, current #ow, debris #ow, and over#ow on a grounding-line fan. Diamicton forms a continuous unit along the top of the section, grading laterally from structureless to strati"ed, and has characteristics of subglacial, sediment gravity #ow, and rainout depositional processes. At one site, a fossiliferous diamicton is interpreted to be deposited by rainout through a combination of suspension settling from meltwater plumes and ice rafting, with subsequent modi"cation by sediment gravity #ow on the fan slope. A radiocarbon date of 13,680$90 BP (Beta-120124) on paired shells from this diamicton is interpreted to represent the date of its emplacement. This date lies within the range of all other dates (&13.1}14 ka BP) on marine organisms from sediments along the coast of southern St. George’s Bay, and suggests that deposition of the diamicton was contemporaneous with sedimentation in all areas along the coast. Evidence to support a previously interpreted late-glacial readvance at&12.6 ka BP was not found. ( 2000 Elsevier Science Ltd and INQUA. All rights reserved. 1.

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.
