Abstract
The Port Askaig Formation is a thick glacigenic succession within the Dalradian \nSupergroup that consists of over 700 m of variably dolomitic diamictite, conglomerate, \nsandstone mudstone and minor dolomite, and is bounded by mixed siliciclastic-carbonate \nsuccessions of the Islay (Lossit) and Bonahaven Formations. These strata are exposed in the \nmetamorphic Caledonides of Scotland, though excellent preservation of sedimentary structures \ncan be found at several sites. An extensional setting for this succession has been proposed based \non stratigraphic and structural arguments. Available chemostratigraphic data includes Chemical \nIndex of Alteration, 13C and strontium isotope values. Palaeomagnetic analyses have shown to \nbe subject to post-depositional Caledonian overprinting. There is also continued debate over the \nregional palaeogeographic reconstructions of the Scottish promontory for this time period. The \nsuccession is chronologically poorly constrained with U-Pb analyses of stratigraphically much \nhigher or lower deposits. The thick succession is thought to record glacially influenced marine \nsedimentation and reworking of unstable sediments in a tectonically active setting with evidence \nof ice-margin fluctuations. Alternative palaeoenvironmental interpretations that focus on glacial \nterrestrial processes and emphasize climatic influence instead of tectonic activity have also been \nproposed. The overlying carbonate is a lithologically diverse coastal complex and so does not fit the Neoproterozoic norm. Research has to date focused on the stratigraphic and \nsedimentological aspects of this succession, as well as some of the broader palaeogeographic and \nstructural features of the Dalradian basin. Future efforts should focus on the chronological, \nstructural and palaeogeographic constraints of this succession.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
