Characterization of the deformation of the Jurassic-Cretaceous deposits of the Toulouk sector (Tim Mersoï basin, North Niger), relation with the uranium mineralizations
Bibliographic record
Abstract
The Toulouk sector, located in the Tim Mersoï basin, is a particular area due to the presence of a Horst structure within the vast expanses of the Irhazer mudstones. This structure has shown sub-surface uranium mineralization. This raises the problem of understanding the deformation of this sector as well as the mechanisms that favoured the establishment of these mineralizations. Thus, the approach implemented consisted in: · Filed work, analysis of satellite imagery data, cartographic and logging data, · A correlation of geological and logging data, This approach allowed the establishment of a local lithostratigraphic framework and the visualization of the uranium distribution and copper mineralization in this sector. It appears from this work that the Toulouk sector would be subjected to an extensive synsedimentary phase that would have favored a structuring in horst and half-graben. The latter would have favored the development of several tectonic structures. These served as drains for the mineralizing fluids.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
