Yardangs in Ancient, Reddened Aeolian Sands South of Mogadishu, Somalia
Bibliographic record
Abstract
Yardangs in quartz-feldspar, reddened dune sands (Brava sands) south of Mogadishu, Somalia, have been produced by east-northeast winds transporting beach sand during the northeast monsoon dry season. The yardangs are developed obliquely in dune flanks sloping 10-20° to the south. Porites coral (82 ±6 ka) from the Ras Aw Maki calcarenite, deposited during marine isotope substage 5a, suggests that the easternmost Brava dunes, which appear to inter-finger or overlie it, are younger than 80 ka. The most important post-depositional change in the Brava sands that allowed yardangs to form was the addition of authigenic kaolinite clay by weathering of feldspars and hornblende.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
