ESTUDOS ISOTOPICOS DE VEIOS DE CARBONATO DA MINA CABAÇAL, MATO GROSSO, BRASIL
Bibliographic record
Abstract
The Cabacal gold mineralizations are enclosed within Volcaniclastic rocks of the Alto Jauru Greenstone Belt. Carbonate and quartz-carbonate veins are common associated with the mineralized zone. Calcite is the only carbonate mineral in these veins that are divided in two groups: lenticular or slightly sigmoidal veins that cross cut the main schistosity in a low angle, and fine veins that occur in swarms, cross cut the main rock schistosity, but in a high angle (±90°). Carbon and oxygen isotope data, as well as 87 Sr/ Sr 86 ratios of the Cabacal carbonate veins indicate that the first group of veins, and the quartz-carbonate veins are related to igneous processes. The second group is believed to have been formed by metamorphic or meteoric fluids, which percolate through extension fractures and interacted with the country rocks after the cessation of the tectonic processes.

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.
