Stratal Architecture and Temporal Evolution of a Passive Margin Mass-Transport Deposit, Neoproterozoic Isaac Formation, Cariboo Mountains, British Columbia, Canada
Bibliographic record
Abstract
Abstract Abstract: Deep-marine strata of the Windermere Supergroup, which currently are exposed in an area over 35,000 km 2in the southern Canadian Cordillera, were deposited on the passive margin of Neoproterozoic western North America. In the Isaac Formation at the Castle Creek study area, stratigraphic evidence of slope instability occurs as mass-movement (slump and slide) and cohesive-debris-flow deposits that crop out locally through the 1.5-km-thick succession. These deposits are particularly common in a mass-transport deposit (MTD) up to 110 m thick that occurs sandwiched between two major channel complexes. Interstratified within these deposits are common coarse-grained channel fills that preferentially infilled irregular topography on the seafloor. In many instances, this irregular topography was most probably related to earlier emplacement of debris-flow and slump and slide deposits. Important stratigraphic characteristics in this succession suggest that this particular MTD represents a major change in the nature of sediment supply and transport and depositional processes within the basin. These changes are interpreted to be controlled principally by changes of relative sea level, which had a first-order control on sediment supply, sediment caliber, and sediment composition to the slope and more distal basin floor.

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.
