Abstract

fetched live from OpenAlex

Terra Nova, 00, 000–000, 2010 Based on high-resolution topography data and the geometry of geological contact traces at the surface, we determined the orientation of layer interfaces of the Sudbury Igneous Complex (SIC). Our analysis provides, for the first time, quantitative structural evidence for the thickness variation of its layers, which supports an impact melt origin of the SIC. The present crater floor topography varies up to 400 m over distances of hundreds of metres to a few kilometres, and up to 1500 m over a distance of about 25 km. Crater floor depressions are spatially associated with economically important sulphide mineral deposits, which points to a viable exploration strategy. Finally, observed variations in the width of the thermal aureole imparted by the SIC on its host rocks are due to primary thickness variations of the SIC rather than post-impact deformation.

Full frame distilled prediction

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.
