Multidisciplinary evaluation of the carbonatehosted Mississippi Valley-type Pb-Zn potential of northern Alberta
Bibliographic record
Abstract
A multidisciplinary study of Middle and Upper Devonian carbonate sequences in northern Alberta (north of latitude 56?30'N) suggests two areas with increased potential for Mississippi Valley-type lead-zinc deposits. The first is Vermilion Chutes on the Peace River. Encouraging data for this region include 1) a Precambrian basement high; 2) the porous, bitumen-stained, and vuggy character (late calcite and dolomite cements) of the Upper Devonian upper Mikkwa and overlying Grosmont formations; and 3) a possible basement-derived structural trend in the Devonian cover that might provide access for deepsourced metalliferous fluids. The second area is along the Clearwater River near Whitemud Falls, east of Fort McMurray, where the Middle Devonian Methy Formation is exposed. Encouraging data here include 1) two structural highs in the Keg River Formation (Methy Formation equivalent); 2) the presence of minor amounts of saddle dolomite cement; and 3) the locally oxide-altered and faulted character of the Methy outcrop.

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.
