Sedimentology of Triassic siliciclastic strata, Mount Martin and Mount Merrill map areas, Yukon Territory
Bibliographic record
Abstract
In the Mount Martin and Mount Merrill map areas, Yukon Territory, 300 to 400 m of interbedded shale, siltstone, and sandstone are preserved between the top of the Permian Fantasque Formation and the base of Cretaceous strata (Chinkeh and Garbutt formations). Based upon two detailed strati-graphic sections, preliminary sedimentological and stratigraphic study of this succession has been undertaken. Five facies associations are recognized, and are interpreted to record deposition on a wave-dominated siliciclastic shelf in environments ranging from distal shelf to upper shoreface. Upward- coarsening packages (10-40 m thick) are common. The succession can be roughly subdivided into four units. In ascending order these are a basal, recessive (shale-dominated?) unit, a sandstone-rich unit, a shale-rich unit, and an upper unit containing sandstone and shale in subequal proportions. Regional comparison of stratigraphic position, lithology, and trace-fossil assemblages suggests a tentative correlation with the Lower to Middle Triassic Toad Formation.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
