(2002) present 129I analyses of hypersaline brines from the Con gold mine in Yellowknife (Northwest Territories). The authors assume that the 129I formed by 238U fission within the metabasalt host rocks and diffused from the rock matrix into the fracture fluid, explaining its present concentration therein. Knowing the U concentration in the metabasalt, the authors apply the in situ 129I production and migration model developed for the Stripa granite by Fabryka-Martin et al. (1989) and argue that the 238U-129I system in the Precambrian shield achieved secular equilibrium, indicating a residence...

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.
