Abstract

fetched live from OpenAlex

Uranium deposits in the Athabasca Basin, northern Canada, are associated with graphitic metasediments and faults zones in the Archean basement and are often “blind”, covered by hundreds of meters of resistive Proterozoic sandstones. Hence airborne electromagnetics (EM) is commonly used in initial exploration over large areas. In recent years new airborne EM systems have become commercially available which have the capability to detect large graphitic zones in or near the basement at depths approaching 1000 m, examples of which are in this paper. Conductivity depth inversions and forward modeling of graphitic conductors in a conductive half‐space are important tools in interpretation as they provide quantitative confirmation that deep conductors are responsible for the observed responses.

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.

Teacher imitation

Not 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.
