Sn and Cu in melt inclusions of the Albernoa felsic volcanic centre, Iberian Pyrite Belt, Portugal : seeking for the missing (magmatic) link
Bibliographic record
Abstract
The Iberian Pyrite Belt (IPB), in the south of Portugal and Spain, hosts several of the largest volcanic-hosted massive sulfide deposits ever known, in a Late Devonian to Lower Carboniferous bimodal-siliciclastic volcanic-sedimentary succession. The architecture of the felsic volcanic centres includes lavas/domes, pyroclastic units and intrusions, defining lava-cryptodome-pumice cone volcanoes (Rosa, C. et al., 2007). Recent lead, strontium, neodymium and osmium isotope data suggest that, besides leaching of metals from the only partially known footwall volcanic and meta-sedimentary sequences, direct magmatic metal contributions may have been significant in some IPB ore-forming systems (Relvas et al., 2006; and references therein). However, direct evidence for this is still lacking and the magmatic link is still to be established.

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.
