Alluvial fan development during the Holocene in the Qu'Appelle Valley, Saskatchewan
Bibliographic record
Abstract
Alluvial fan sediments contain valuable information on environmental change and anthropogenic influences, and function as an archive of landscape development. The purpose of this paper is to describe the analysis of the sedimentary information from core samples taken from two alluvial fans in the Saskatchewan prairies. The analysis assessed grain size, organic matter content, and microfossil presence to identify periods of accumulation and stabilization. Parker, Beavers, and Product weathering indices were used to analyze the modern source soil samples and the borehole cores to determine weathering/leaching conditions. The bed‐load transport sediments showed a higher leaching intensity whereas lower leaching was revealed for periods of stability, silt sheet flows, and sand sheet flows. The Beavers Index was not only a strong indicator of a bed‐load transport layer, but also of calcium accumulation zones marking alluvial fan surface stability. The large Dolomite/Calcite ratio marking the calcium accumulation zones was used for correlation between the two alluvial fan sites on a regional scale. A comparison of the stratigraphy of the two alluvial fans documents that a relationship exists between agriculture and an increase in erosion.

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.
