Stuctural and stratigraphic controls on Zn-Pb-Ag mineralization at the Nanisivik Mississippi Valley-type deposit, northern Baffin Island, Nunavut
Bibliographic record
Abstract
The Nanisivik Mississippi Valley-type Zn-Pb-Ag deposit is located on northern Baffin Island, Nunavut. Mesoproterozoic strata in the Nanisivik area consist of a basal siliciclastic succession (Adams Sound and Arctic Bay formations), platformal carbonate deposits (Society Cliffs and Victor Bay formations),and a molasse deposit (Strathcona Sound Formation). These strata are cut by east-trending normal faults interpreted as the conduits for mineralizing fluids that formed the Nanisivik massive sulphide deposits.Mineralization is localized within broad anticlines, proximal to normal faults, and is hosted by rocks of the upper and uppermost middle Society Cliffs Formation. Sulphide precipitation is interpreted to be primarily the result of reduction of ascending metalliferous fluids by previously trapped hydrocarbons. Exploration criteria for the selection of areas prospective for additional Nanisivik-style mineralization include stratigraphic, structural, and fluid-flow considerations.

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.
