Sedimentary and Stratigraphic Analysis of the Viking Sand in the Edgerton/Wainwright Area, Central Alberta* By
Bibliographic record
Abstract
The Viking Formation was deposited within the Western Canadian foreland basin during Albian time, Early Cretaceous. This study examines the lithology, sedimentary facies, and stratigraphy of the Viking Formation in the Edgerton / Wainwright area (NW corner 45-5W4 to SE corner 44-4W4) of central Alberta. The studied section is comprised of, in ascending order, marine offshore shales of the Joli Fou Formation, marine sandstones of the Viking Formation, marine shales of the Westgate Formation, to the Base Fish Scales Marker. within the Viking Formation. The Viking Sand unit was deposited as a thin sand sheet in a shoreface environment during a lowstand, related to a forced regression. In cores, the Viking Sand unit is demarcated by burrows in-filled with coarse-grained sediments beds of rip-up clasts and structureless sands lenses (up to 5cm). The base of the Viking Sand unit can be interpreted as a Regressive Surface of Marine Erosion (RSME) as coarse shoreface sands overlie offshore transitional sediments with a sharp contact between the two facies. During a following transgression, parts of the lowstand shoreface deposits became subsequently reworked and redistributed to form linear sand bodies (i.e., Viking Sand unit) trending NW-SE, creating a Transgressive Surface of Erosion (TSE). The TSE is overlain by offshore transitional sediments, which where deposited during a subsequent sea level stillstand. The upper boundary of the Viking Formation is a basin-wide Transgressive Surface of Erosion (TSE), marking the end of Viking deposition and onset of deposition of marine shales of the Westgate 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.
