CONTRASTING FERRIC IRON CONTENTS IN CONJUGATE Fe OXIDE AND SILICATE MELTS FROM SOUTHERN SLOVAKIA DETERMINED USING MICRO-XANES SPECTROSCOPY
Bibliographic record
Abstract
Globules of quenched Fe-oxide melt (63–75 wt% FeO tot , 5–13 wt% SiO 2 ) are found in syenite xenoliths ejected during phreatomagmatic eruptions near Pincina in southern Slovakia. The xenoliths represent flotation cumulates formed during fractionation of alkali basaltic magma in the deep crust. Micro-XANES spectra reveal only ferric iron in the Fe oxide globules and dominantly ferrous iron in the associated trachytic glass (6–10% FeO tot , 62–66 % SiO 2 ,), thus indicating almost complete disproportionation of Fe 2+ and Fe 3+ during the immiscible separation of the two melt phases. If taking place at an earlier stage of the magmatic differentiation, segregation of the Fe oxide phase could lead to significant change of the oxidation potential of the residual silicic melt.

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.
