Annual paleomagnetic record from late glacial varves in Lago Buenos Aires Valley, Patagonia, Argentina
Bibliographic record
Abstract
A sequence of 887 varves has been measured. A continuous process of ice retreat is inferred through the gradual decreasing of the thickness of the varves. Paleomagnetic studies show very strong intensities and stable polarity within single varves as well as from varve to varve. The general trend of declination is a smooth shift from 40–50°W to 0° at the top. The inclination shifts from -70°–85° to -35° at the top. The VGP is localized in the Arctic-Siberian region and swings later to western Greenland-northeastern Canada. The age of the varves is on the range between 12,500–13,500 BP. Una secuencia de 887 varves ha sido medida. Un proceso continuo de recesión glacial puede inferirse a través de la disminución gradual del espesor de los varves. Los estudios paleomagnéticos muestran intensidades muy fuertes y polaridad estable en varves individuales, así como de varve a varve. La tendencia general de la declinación es una variación suave de 40°–50°W, a 0° en el techo de la secuencia. La inclinación varia de -70°–85° a -35° en el techo. El PGV está localizado en la región ártico-siberiana y se desplaza luego hacia Groenlandia occidental o Canadá nororiental. La edad de les varves parece encontrarse en el rango entre 12.500–13.500 años AP.

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.
