Abstract

fetched live from OpenAlex

The Corossol crater (50°3’N, 66°23’W) was first discovered by the Canadian Hydrographic Service about 10 years ago while mapping the entrance to the Sept Iles harbour, Gulf of St Lawrence, Canada [1]. It is a complex circular structure about 4 km in diameter with a central uplift that rises to about -70 m and an annular valley ~160 m deep. There are no other circular structures nearby. Figure 1: Bathymetry of the 4-km diameter Corossol crater, Near Sept-Iles, Gulf of St Lawrence, Canada (Canadian Hydrographic Service). The bedrock of this region is the Sept Iles Intrusive suite, an 80 km diameter 564 Ma old layered mafic intrusion [2]. These rocks are overlain by relatively thin flat-lying Ordovician limestones that have only a few, small outcrops in this region [3]. However, the submarine limits of these rocks can be identified from cuestas (steep slopes). One such cuesta marks the northern limit of the crater and continues to both the east and the west. Hence, the crater appears to have formed in these limestones, but may well have been excavated the crystalline basement as well.

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.
