Origin of the Anorthosite-Mangerite Rocks in
Bibliographic record
Abstract
Rocks of the anorthosite-mangerite suite were intruded in many places in the southern part of the Grenville province of the Canadian Shield. These rocks, known as the Morin series in southern Quebec, are described from two contrasted areas, one in which there has been intense deformation during the emplacement of these rocks and in the other only mild deformation. Differences in the mineralogy and chemistry of these rocks in the two areas can be related to the degree of deformation. Although many of the rocks of the series still retain their igneous textures, others, especially the mangerites, are largely recrystallized and commonly exhibit a gneissic foliation. The feld-spars and pyroxenes which are by far the most abundant minerals of the Morin series are dealt with in detail. From a study of the coexisting pyroxenes and the amount of iron in the plagioclases, evidence is given for a difference in the degree of metamorphism between the two areas. All of the pyroxenes from the more highly deformed area contain considerably more alumina than those from the other area. Coexisting lime-rich and lime-poor pyroxenes are characteristic of almost all of the rocks of the series. The coexistence of subcalcic ferro-

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.
