Abstract
Sedimentary phosphate occurs as thin nodular beds and nodular disseminations in the Dange Formation (Paleocene) of Sokoto basin in north western Nigeria. The geochemistry, origin and reserve evaluation of the phosphate in the Kasarwasa Prospect have been undertaken. Analysis indicates P2O5 values of 29.23-34.2%. The nodules are suitable for the production of fertilizers on the basis of major elements and P2O5 values. The nodules also have direct soil application potential. Origin of the nodules was from direct precipitation as microsporite which was later reworked. The origin was associated with the trans-Saharan Tethys Sea transgression in North Africa. A nodule reserve in the Kasarwasa Prospect was evaluated from 46 pits. Tonnages per acre range from 91.14 to 3,260.09 which indicate only two hectares are economic while 22 are non-economic deposits.

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
