Gravimetric and Magnetic interpretation of Catalão II anomaly (GO-Brazil)
Bibliographic record
Abstract
Catalão II anomaly is located approximately 14 Km from the ultramafic-alcaline-carbonatite complex Catalão I which is a very important site explored by mineral companies in the extraction of phosphate, niobium, rare earth, titanium and vermiculite. The geophysical modeling of Catalão II anomaly can help to understand if there is a relationship between Catalão I and Catalão II intrusions and also evaluate the shape of the body itself. The Geophysical Inversion Facility of the University of British Columbia (UBC-GIF, mag3d and grav3d programs) were used to invert the magnetic and gravimetric data. The resultant susceptibility and density models from both methods were compared in the same mesh and confronted with the geological knowledge of the anomaly. The outcome models agree with the expected contrasts and the overall result can be used for a preliminary estimation of the anomaly and motivate a more detailed investigation over all the complex area.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
