Speciation of Nb and Ta in magmatic-hydrothermal titanite and ilmenite: Insights from combined SXAS and XPS analyses and implications for Nb/Ta systematics
Bibliographic record
Abstract
The supporting information in this document contains captions for Figures. S1 and S2 (*jpeg), captions for Tables S1 to S7 (*xlsx), as well as references from the supporting information. Tables S1-S7. Raw dataset for Figure 2-8. Fig. S1. (a) Sketched map showing the location of Qinling Orogenic Belt; (b) The distribution of Nb-REE deposits associated with alkaline rocks and carbonatites. The locations of the Fangcheng and Ziyang Nb deposits are marked with red boxes. Fig. S2 Measurements of the Nb K-edge of Nb compounds as well as natural and synthetic Nb-bearing minerals reported in literature in XANES (X-ray adsorption near-edge) spectra have been assembled here (after Martin and Wülser , 2014).
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.
