Analysis and reprocessing of airborne gravity gradiometer data over the Strange Lake rare Earth deposit, Québec-Labrador
Bibliographic record
Abstract
A high-resolution airborne gravity gradiometer survey was flown in March 2012 over the Strange Lake intrusive complex, located on the border of Québec and Newfoundland and Labrador. This survey provided an opportunity to better understand the performance and limitations of this technology and also investigate potential improvements to the associated data processing. Airborne gravity gradient data low-pass-filtered at 75 m, rather than the standard 300 m, were provided by the contractor for this purpose. One flight line was reflown several times and used to assess the repeatability of the data, showing that in this particular area, the airborne gradient gravity system has a full-sine (wavelength) resolution of about 700 m. The system can therefore detect anomalies having a width of about 350 m. We also found that for gradiometer data, kriging is a better interpolator than low-pass filtering combined with minimum curvature gridding. Using kriging, line-to-line correlation (and in some cases, resolution) appears slightly improved.

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.
