Abstract
Newly discovered palaeosols in the Gaskiers Formation of Newfoundland provide a new perspective on its palaeoenvironment, and are evidence that it was not a deep submarine tillite, nor an anoxic deep-sea floor, nor a ‘cap carbonate’ from extreme geochemical perturbation of the global ocean. Discovery of oxidized palaeosols and re-evaluation of sedimentary facies and stratigraphic relationships now suggest reinterpretation as a coastal plain with glacial moraines in the forearc basin of a continental volcanic arc, like modern Japan. Ediacaran palaeosols of the Gaskiers Formation lack large root traces, but show soil profile differentiation (clay enrichment and depletion of alkali and alkaline earth elements at the expense of feldspar and rock fragments) and diagnostic soil structures (blocky peds, argillans, sepic plasmic fabric). These palaeosols are evidence of a humid temperate climate and marked marine regression accompanying the Gaskiers Glaciation of the early Ediacaran (580 Ma). Geochemical weathering trends in the palaeosols, especially phosphorus depletion, are characteristic of biologically active soils. Ediacaran microbial earth ecoystems may have been responsible for filamentous disruption of bedding in the palaeosols.

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.
