Hiortdahlite II from the Ilímaussaq alkaline complex, South Greenland, the Tamazeght complex, Morocco, and the Iles de Los, Guinea
Bibliographic record
Abstract
At Ilímaussaq hiortdahlite has only been known from a dyke located immediately to the south-east of the complex. This mineral has now been found in a pegmatite horizon in the sodalite-rich rock naujaite of the complex. It appears to be earlier than eudialyte and is regarded as having been formed at low alkalinity at an early stage of naujaite formation. The optical and X-ray parameters are identical to the data for hiortdahlite from Kipawa, Quebec, and indicate that the Ilímaussaq mineral is type II hiortdahlite. Minerals from the Iles de Los, Guinea, and the Tamazeght complex, Morocco, have been examined by optical and X-ray methods and chemical analysis, and are shown also to be hiortdahlite II.

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.
