Subsurface compressional structures and facies transitions imaged by seismic reflection data, eastern margin of Richardson Trough, Peel Plateau, Yukon
Bibliographic record
Abstract
Abstract Knowledge of the deformation front of the Richardson Anticlinorium is an important component of assessments for regional hydrocarbon potential; but sparse outcrop in the Peel Plateau, Yukon has made geological interpretations difficult and the results of reconnaissance mapping uncertain. To date, a single fault has been inferred to define the eastern limit of deformation. In this paper, we present stratigraphic and structural interpretations of multi-channel seismic reflection data collected in an early phase of hydrocarbon exploration. Early Tertiary deformation is expressed as a series of thrust faults, folds and back thrusts, not a single through-going fault. Deformation has been concentrated on several lithologic transitions: a pinch out of syn-rift sandstones and the transition from carbonate platform to basinal shales. The Middle Ordovician to Middle Devonian eastern margin of the Richardson Trough is imaged as clinoforms and a carbonate buildup; clinoforms can be mapped about 75 km along strike. Integration with aeromagnetic data allows us to construct a map of subsurface structures along the eastern deformation front associated with the Richardson Anticlinorium. Faulted anticlines and facies pinch outs are potential traps although any play in this region remains hypothetical.

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.
