Pore-size distribution for graphitic shale samples from the Astarte River formation, Piling Group, Baffin Island, Nunavut
Bibliographic record
Abstract
Pore-size distribution analysis was performed on four graphitic shale samples from the Astarte River formation, Baffin Island, Nunavut. This included measurement and interpretation of pore-size distribution data obtained by mercury injection porosimetry. The purpose was to document the results of the pore-size analysis and to provide pore-structure information on the graphitic shale. These would eventually be used for electrical mechanism analysis and geophysical survey interpretation. Effective porosity values determined by mercury porosimetry (öHg1 and öHg2) were in the ranges of 3.47 - 14.2%. The storage and connecting porosity values (ös and öc) were in the ranges of 2.72 - 12.8% and 1.03 - 2.29%, respectively. The sulphide-rich samples have the lowest porosity values (3.5 - 4.2%). The samples with higher porosities (sample numbers BAF-1 and BAF-2) have pore-size distribution patterns that resemble those of typical mudstone. The samples with lower porosity values (BAF-3 and BAF-AB) have more similarities to crystalline rocks.

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.
