Abstract
Abstract In the Gulf of Mexico and adjacent landmasses, faults are very complex, and their distribution is closely related to plate tectonics, ocean–land boundary, and former structure. The plane position of the faults can be identified by the maximum characteristic of the vertical derivative of the normalized vertical derivative of the total horizontal derivative (NVDR‐THDR) of the Bouguer gravity anomaly. The apparent depth of the faults is inverted by the Bouguer gravity anomaly curvature property. Based on tectonic evolutionary processes and the plane distribution and apparent depth characteristics of the faults, a complete fault system for the Gulf of Mexico and adjacent areas has been established, including 102 faults. The apparent depths of 33 first‐class faults are 16–20 km and for 69 second‐class faults are 12–16 km. The F 1‐2 and F 1‐3 subduction fault zones are two caused by the subduction of the Cocos Plate into the old Yucatan and Chorti landmasses; F 1‐11 and F 1‐12 fault zones extend westward to the coast of Guatemala and do not extend into the continent; F 1‐17 and F 1‐20 faults, which control the boundary of the oceanic crust, do not extend southward into the continent. The fault system, which radiates in a “fan‐shaped” structure as a whole, unfolds to the northeast. Faults of different nature and sizes are distributed in the Cocos Plate subduction zone, Continental, Gulf of Mexico, Yucatan old landmass and Caribbean Plate in NW, NNW, NS, NE and NEE directions. In the Gulf of Mexico region, the fault system is a comprehensive reflection of former tectonic movements, such as plate movement, drift of old landmasses and expansion of oceanic crusts. The first‐class faults control the plate and ocean–continental boundaries. The second‐class faults are subordinate to the first‐class faults or related to the distribution of different sedimentary layers.

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
