Abstract
Micromorphology is the study of arrangements of particles and matrix and is primarily carried out using thin sections. It is a useful tool to characterize sedimentary facies because material is not disaggregated and the particles are examined in their original position relative to other particles, thus increasing the reliability of sedimentological interpretations. This technical note presents a method for the impregnation of marine sediment core subsamples for the preparation of thin sections. To achieve this, the pore water has to be replaced by an epoxy resin. The method consists of five main steps, described in detail: subsampling preparation; subsampling; sediment dehydration; impregnation; and drying and cutting.

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
