Sequence Stratigraphy and Provenance of the Bakken Formation in Southeast Alberta and Southwest Saskatchewan
Bibliographic record
Abstract
Three transgressive-regressive systems tracts are interpreted in the Bakken Formation in southeastern Alberta and southwestern Saskatchewan based on analysis of cores and well logs. These systems tracts include a basal transgressive systems tract TST1, a regressive systems tract RST and a transgressive systems tract TST2. Three distinct systems tracts are interpreted within Bakken RST; these are high stand systems tract (HST), Falling stage systems tract (FSST) interpreted within the Bakken Formation and a lowstand systems tract within the Exshaw Formation to the west. Fluctuations in base level that resulted from changes in relative sea level and tectonics controlled the deposition of the Bakken Formation. Detrital zircon geochronology and reworked conodonts from the Bakken middle member indicate sediment transport from multiple sources. Thrust-belt sources associated with the Franklinian Orogeny to the north and northeast contributed the majority (no less than 25%) of the Bakken clastic budget. The two mechanisms for Bakken sediments delivery are continental scale fluvial systems and longshore drift of sediments.
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.
