Abstract
Magnetotelluric data have been recorded along two traverses in southern Western Australia. The survey locations were chosen so as to define conductivity structure in the deep crust and upper mantle across fundamental geological boundaries within and at the margin of the Yilgarn Craton. Data across the suture zone between the Archean Yilgarn Craton and the adjacent Proterozoic Albany-Fraser Orogen suggest major structures and crustal blocks have been successfully mapped based on their conductivity characteristics. The data are interpreted as showing the orogen is largely allochthonous and the suture zone may contain remanent oceanic crust and suspect terranes of continental affinity. Preliminary results from a survey across the southern Yilgarn Craton from the Southern Cross to Eastern Goldfields greenstone terrains suggest major fault structures, such as the Koolyanobbing shear zone, extend in to the deep crust and dip to the east. A zone of anomalously conductive mantle occurs beneath the Lake Johnston greenstone belt. This belt contains nickel sulphide deposits but the origin and significance of the mantle feature and any link to the mineralisation remains equivocal.

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 it
