Abstract

fetched live from OpenAlex

Abstract The study of geomorphic processes in barren landscapes, Precambrian and modern, has wide implications for planetary science. A long‐held status quo has been that, prior to the Palaeozoic evolution of vegetation, fluvial channels would have been invariably shallow, wide, braided in planform and flashier in discharge than vegetated ones. These assumptions are challenged through a threefold analysis of channel morphometry, discharge regimes and planform style. Measurements of modern and Proterozoic channel sections reveal overlapping morphometric ranges irrespective of climate and vegetation, pointing to shared scalar properties. Discharge regimes and planform styles inferred from Proterozoic records are akin to the spectrum observed in modern systems. Current criteria employed to identify meandering planforms are biased towards mud‐prone systems, and fail to address the sand‐rich nature of prevegetation alluvium. Vegetation forcing on river functioning cannot be entirely downplayed, although available data are construed towards an uniformitarian appraisal of pre‐Silurian fluvial dynamics.

Full frame distilled prediction

Teacher imitation

Not 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.
