Canadian Mineralogist Vol. 23, pp.263-271 (1985) ELECTRON.MICROPROBE ANALYSIS OF MINERALS FOR RARE.E^ARTH ELEMENTS: USE OF CALCULATED PEAK-OVERLAP CORRECTIONS
Bibliographic record
Abstract
The relative intensities of the lcr1, Lgy L/z, LB3, and.L71 lines were measured using ten R.EE phosphates. These data were used to calculate peak-overlap corrections for the Lal and Lp1 lines of RE'8. Wavelength-dispersion and energy-dispersion specfia of the Z lines of fourteen R.EE compare favorably with the spectra using the peak-overlap corrections. Detection of REE by microprobe analysis is best accomplished by first collecting a wavelength-dispersion spectrum to identify interfering elements and locate the best wavelengths for background measurements, The,REf phosphates were used as standards for wavelength-dispersion analysis of four silicate glasses pre-pared by Drake & Weill (1972), three silicate glasses pre-pared in the.present study and some minerals previously analyzed for REE by wet+hemical metlod. The microprobe results of these samples axe consistent with the known levels of REE in the samples.

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.
