Bibliographic record
Abstract
This paper presents an integrated approach to geological mapping, by the use of old airborne geophysical data. The data processing and interpretation allowed the use of the Brazil - Canada Geophysical Project for much more comprehensive understanding of the regional and local geology. The interpretation of airborne magnetics has provided both an overview of the regional structure as well as further insights into the structural controls of the Crixas-Cedrolina region. The four radiometric maps (total count, potassium, uranium and thorium) were individually enhanced by manipulation of their histograms and then displayed in pseudo-color, as ternary displays (R:G:B = K:Th:U). Individual lithological units can be traced due to their distinctive radiometric response. Ground magnetics profile provided good results identifying detailed location for the boundary. This kind of approach is fundamental for investigating the regional structural framework and helps to better define the boundaries of the different lilhostratigraphic units present in Precambrian terranes.

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.
