An updated compilation of radiocarbon dates relating to the age of sensitive-clay landslides in the Ottawa Valley, Ontario-Quebec
Bibliographic record
Abstract
This Open File is an updated compilation of 167 published and unpublished radiocarbon dates relating directly or indirectly to the ages of 45 landslides or landslide complexes in sensitive clay, and three 'disturbed terrain' features in the Ottawa Valley, southeastern Ontario/southwestern Quebec. Twenty-three tables contain dates for individual landslides (or disturbed terrains), or the dates for multiple landslides within a specific geographical area. Each table is proceeded by a short summary that overviews the landslide or disturbed terrain, and the associated radiocarbon dates. Each table lists the attributes of the dates, including sampling location, dated material, dating results, and contextual information on the ages and the landslide/disturbed terrain. The geographical coordinates, radiocarbon age, and laboratory number of each date are listed in two spreadsheet files (.xlsx and .csv formats) in the Appendix. The radiocarbon age dataset in this Open File will aid future studies investigating the chronology of prehistoric landslides in sensitive clay within the Ottawa Valley and St. Lawrence Lowlands region.
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.

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.
