Abstract
Veblenite, ideally KNa(Fe 2+ 5 Fe 3+ 4 Mn 7 )Nb 4 (Si 2 O 7 ) 2 (Si 8 O 22 ) 2 O 6 (OH) 10 (H 2 O) 3 , triclicnic, P1, a 5.3761(3), b 27.5062(11), c 18.6972(9) , 140.301(3), 93.033(3), 95.664(3) , V 1720.96(14) 3 , has no natural or synthetic analogues. It is a new mineral occurring at Ten Mile Lake, Seal Lake area, Labrador, Newfoundland, Canada, as red brown single laths and fibres included in feldspar. In the crystal structure of veblenite, M octahedra share common edges to form a wavy octahedral sheet parallel to (001). SiO 4 tetrahedra share corners to form Si 2 O 7 groups and Si 8 O 22 ribbons. This is the first occurrence of an eightmembered Si-O ribbon in a mineral crystal structure. The Nb-dominant D octahedra, Si 2 O 7 groups and Si 8 O 22 ribbons share common vertices to form a heteropolyhedral (H) sheet. Two H sheets and an O sheet constitute an HOH block. Along [001], HOH blocks connect via common vertices of D octahedra and cations at the A(1,2) and B interstitial sites. In the intermediate space between two adjacent HOH blocks, two [100] channels of different size can be identified. A narrow channel of the width of an Si 2 O 7 group contains the A(1) site mainly occupied by K. A large channel has the width of four Si 2 O 7 groups (Si 8 O 22 ribbon) and contains A(2) sites partly occupied by K and H 2 O groups.

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.
