Abstract
Abstract Water-escape and gas-escape structures were generated in the laboratory to assess variations in deformational structures generated during these events. Particulate fluidization was observed to be the method by which grains were redistributed during water escape. Resulting structures of particulate fluidization comprised disrupted and downward-deflected primary laminations, and a massive-appearing column of sand above the point source. Gas experiments, with a low flow rate (6.167 × 10−6 m3/s) allowed gas to disperse through fractures, and only subtle deformation was achieved. Aggregative fluidization (i.e., fluid movement through sediment as bubbles) was the mechanism for grain displacement during gas escape. With increased flow rate (7.67 × 10−5 m3/s) aggregative fluidization occurred and particles were carried upward in the wake of the passing gas bubble. Aggregative fluidization resulted in broken, upwards-warping laminations and convoluted bedding. Experiments illustrate a significant morphological difference between water escape and gas escape. Water-escape structures were bounded by downwards-warping laminations, consistent with water-escape structures encountered in the rock record. Gas-escape structures displayed upwards-warping laminations, and could represent a formation mechanism for convolute bedding.

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
