Tephra geochemistry of the Ibex Hollow Tuff, a 12-Ma super-eruption
Bibliographic record
Abstract
These tables contain geochemical data collected for tephra samples either correlated with or in the same type section with the Ibex Hollow Tuff. Most samples were collected by Andrei Sarna-Wojcicki and Mike Perkins, but some were submitted to the U.S. Geological Survey Tephrochronology Project for analysis by other persons. Electron microprobe analysis (EMA) was performed at the U.S. Geological Survey in Menlo Park California, at the University of Utah in Salt Lake City Utah, and at the University of Toronto in Toronto Ontario Canada. Bulk glass EMA results have been normalized to 100% anhydrous following standard normalization procedures. Individual shard analyses are unnormalized. Instrumental neutron activation analysis (INAA) was conducted at the USGS in Lakewood, Colorado. These analyses have not been normalized. Laser ablation inductively-coupled plasma mass spectroscopy (ICP-MS) analyses were conducted at at the Department of Earth Sciences, University of Toronto. No normalization has been applied to these data.
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.
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; both teacher heads agree on what is shown here.
