NOTES 475 A LONG-AXIS CLAST FABRIC COMPARISON OF THE SQUANTUM "TILLITE', MASSACHUSETTS AND THE GOWGANDA FORMATION
Bibliographic record
Abstract
Long-axis clast fabrics from the diamictites of the Squantum "Tillite " in Massachusetts and the Gowganda Formation of Ontario are dissimilar in their general features. The Squantum fabrics have well-developed girdles which dip steeply down the paleoslope. The fabrics are most like those of mudflows in their general features but dip considerably more steeply than expected. Modes occur parallel to the strike of the paleoslope, a feature not previously observed in mudflow fabrics. Each of two fabric diagrams from the Gowganda Formation has two subhorizontal modes, one parallel and the other transverse to the paleoslol~e. The modes are contained in broad horizontal girdles. A third fabric diagram from the Gowganda has a single well-developed subhorizontal mode parallel to the strike of the paleoslope. The Gowganda fabrics are most similar to known till fabrics. Thus the fabrics tend to support a mudflow origin for the Squantum "Tillite" and a glacial origin for the Gowganda Formation. This comparison demonstrates the usefulness of long-axis clast fabric as a criterion for the determination f the origin of diamietite deposits.

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.
