Proterozoic Massive Sulfide Replacements in Volcanic Rocks at Jerome, Arizona
Bibliographic record
Abstract
At Jerome, Arizona, mafic volcanics, felsic volcanics, and tuffaceous sedimentary rocks comparable to many Archcan sequences in the Canadian Shield are folded into a north-east trending dome. The northern half of the dome is flexed sharply northwest and its eastern limb is thrust west and upward more than 3,000 feet. Proterozoic quartz por-phyry dikes and bodies of irregular shape and gabbro sheets were eraplaced in volcanic rocks and postdate part of the folding. $ulfides occur in the quartz porphyry and vol-canic rocks and in the U.V.X. mine, along a thrust fault, which ends the eastern exten-sion of gabbro and quartz porphyry sheets on the hanging-wall and the footwall sides, re-spectively, of the United Verde massive sulfide deposit. The relative ages and associa-tions of sulfides, gabbro, and quartz porphyry are interpreted to imply derivation from a common magmatic source.

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.
