A Microscopic Study of Platy and Concretionary Structures in Certain Saskatchewan Soils1
Bibliographic record
Abstract
Thin sections of platy A2 horizons of several Saskatchewan soils which have developed under podzolization or solonization processes were studied A synthetic resin was used to impregnate and fix the soil aggregates so that slides for microscopic study could be made. The thin section studies revealed “banded fabric” in the platy horizons of podzolized soils The platy A2 horizon of a solonetzic soil revealed an “isoband fabric” as did the A2 of a podzolic-solonetzic soil studied. “Wrinkle marks” and “invasion amygdali” (concretions) were also noted in samples from A2 horizons of podzolized soils. A brief discussion of possible modes of formation of these micro-structures as proposed by several authors is included. It is suggested that the thin section technique might well be applied in studying pore space and channel arrangement in soils, as well as aggregates of all types It would also probably be useful in studying such matters as the distribution of organic matter within the soil body. This technique migh...

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.
