Abstract
This handsome color atlas of photomicrographs is similar in some ways to color guides of petrography, heavy minerals, soils, and paleosols published in recent years, but it is in some ways unique. Particularly unique is its subject matter in the terra incognita between the traditions of metamorphic-igneous petrography on the one hand and soil micromorphology on the other hand. Although the book opens with photomicrographs of various little-weathered igneous and metamorphic rocks, most of the photomicrographs are of mineral grains more or less obliterated by weathering or hydrothermal alteration. By the end of the book, most of the photomicrographs are of pisolitic and boxwork textures formed in thick lateritic and bauxitic soils and paleosols with near total destruction of original igneous and metamorphic textures. It is thus a book that will surprise both petrologists, who labor to obtain samples without the alterations illustrated, and pedologists, who deal with less strongly developed soils and paleosols of sedimentary parent materials. The unique focus of this book can best …

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
