Sedimentology, stratigraphy and geochemistry of Sulphur Mountain (Montney equivalent) Formation outcrop in south central Rocky Mountains, Alberta, Canada
Bibliographic record
Abstract
Abstract Deposition of the Lower Triassic Sulphur Mountain Formation of Western Canada was the product of a dynamic interaction of sedimentary processes and tectonism, resulting in highly heterogeneous successions. The Sulphur Mountain Formation, age equivalent to the subsurface Montney Formation, outcrops in South Central Rocky Mountains, Alberta, Canada and provides an opportunity for a high-resolution study. A detailed framework of four studied outcrops was established by integrating sedimentology, stratigraphy, and inorganic geochemistry. Four lithofacies were identified in these outcrops; hummocky cross-stratified very fine sandstone (L-1), massive-appearing very fine sandstone and coarse siltstone (L-2), interlaminated very fine sandstone and siltstone (L-3), and planar laminated siltstone (L-4). Interpreted environments of deposition for these lithofacies range from lower shoreface to proximal offshore. Correlated outcrop measured sections and interpretations of the geochemistry and lithofacies suggest a dynamic and complex depositional history. Changes in relative sea level, source terrain/provenance, and detrital clastic sediment input infer depositional influences during intervals of extensive weathering and tectonic activity. These factors provide an explanation for the facies heterogeneity observed in the Sulphur Mountain Formation.

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.
