Transgressive Sandstone Sedimentology of the Albian Martin House Formation, Peel Region, Northwest Territories
Bibliographic record
Abstract
Excerpt In the Peel Region of NWT the 10-50 m thick Martin House Formation records Albian transgression of the Western Interior Seaway. Martin House Formation comprises up to 3 sandstone units separated by intervals of offshore mudstone. The 5-10 m thick basal sandstone records a transgressive facies succession from upper to lower shoreface sandstones overlain by offshore mudstone. A proposed depositional model for the lower sandstone consists of wave-dominated barrier bar deposits in the west and restricted, tide-influenced deposits in the east. Upper Martin House Formation sandstone units record shoreface progradation from east to west. The uppermost sandstone is overlain by an up to 1 km thickness of Arctic Red Formation offshore mudstone. Within the Martin House Formation reservoir properties are more favourable in eastern, marginal marine sandstones (>15% porosity; >50 mD permeability).
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
