Relationships between the macroscale sedimentology and micromorphology of glacigenic diamictons in south-central British Columbia
Bibliographic record
Abstract
This research explores relationships between the macroscale sedimentology and micromorphology of glacigenic diamictons associated with the last Cordilleran Ice Sheet in south-central B.C., and tests the hypothesis that diamictons classified using traditional definitions and sedimentological criteria have unique micromorphologies. Cluster analyses suggest that diamicton types cannot be differentiated by the relative abundances of particular microstructures. Qualitative analyses suggest that microfabrics may be less consistent with macrofabrics in deformation tills and gravity flow diamictons than in undeformed or partially deformed lodgement tills, and evidence of water sorting at the microscale may be more prevalent in gravity flow diamictons than in primary tills. This suggests that though microstructures and microfabrics are not diagnostic to any one diamicton type, depositional processes express themselves at the microscale. Therefore diamicton micromorphology may be used to elaborate on diamicton depositional mechanics and post-depositional modification; however, interpretations are best made within the context of macroscale sedimentological inferences.

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.
