Preliminary geophysical interpretation of the McKeand River area, southern Baffin Island, Nunavut: insights from gravity, magnetic and geological data
Bibliographic record
Abstract
The recently completed McKeand River and Amittok Lake aeromagnetic surveys on southern Baffin Island, Nunavut pro- \nvide a new high-resolution magnetic dataset over an area with no previous coverage. Complemented by regional gravity \ndata, newly acquired rock-property information and geological-mapping products, the aeromagnetic dataset yields qualita- \ntive and quantitative information on the structure and geology of the underlying bedrock. This paper presents a preliminary \ninterpretation of these datasets that delineates three gravimetric and five magnetic domains. The gravity data outline a broad \nnegative anomaly associated with a plutonic-intrusive suite, as well as several isolated gravity highs associated with \nmetasedimentary strata. Magnetic domains are defined on the basis of anomaly amplitude, wavelength and texture, and are \ncorrelated to the mapped geology and magnetic properties. Associations between potential-field anomalies, physical prop- \nerties and mineral occurrences help define the regional distribution of economically significant horizons.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
