MAGNESIOFOITITE FROM THE URANIUM DEPOSITS OF THE ATHABASCA BASIN, SASKATCHEWAN, CANADA
Bibliographic record
Abstract
Il y a deux generations de tourmaline dans la matrice des breches alterees associees aux gisements d'uranium du bassin d'Athabasca, au Saskatchewan, Canada. La tourmaline precoce se presente en cristaux isoles, tandis que les cristaux tardifs sont representes par des aggregats fibroradies (ou spherulitiques) de cristaux ou des surcroissances sur les cristaux precoces. La tourmaline dans les veines associees ressemble etroitement a la tourmaline de la matrice des roches brechifiees. La proportion des atomes, calculee a partir de donnees obtenues avec une microsonde electronique normalisees sur une base de 15 cations Y + Z + T, montre que la tourmaline precoce est partiellement depourvue de protons, tandis que la tourmaline tardive est fortement depourvue d'alcalins. Si on suppose une proportion stoechiometrique de bore, les formules structurales calculees pour les deux generations de tourmaline au gisement de Rabbit Lake (echantillon R81) sont: Na 0.48 K 0.01 Ca 0.51 (Mg 2.48 Fe 3+ 0.21 Mn 0.01 Ti 0.24 ) Al 5.34 Pe 3+ 0.66 (Si 6.06 )O 18 (BO 3 ) 3 (OH) 2.68 et□ 0.76 Na 021 K 0.01 Ca 0.02 (Mg 2.15 Fe 3+ 0.05 Al 0.80 )Al 6.00 (Si 5.89 Al 0.11 )O 18 (BO 3 ) 3 (OH) 4.01 .Des compositions semblables ont ete observees aux gisements d'uranium de Second Link Lake et Key Lake. Les tourmalines precoces correspondent a une dravite deficitaire en protons, tandis que les tourmalines tardives se rapprochent du pole magnesiofoitite du groupe des tourmalines.

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.
