Preliminary report on the Triassic and Jurassic stratigraphy and paleontology of the Sinwa and Takwahoni formations near Lisadele Lake, Tulsequah map area, northwestern British Columbia
Bibliographic record
Abstract
Asouthwestern outlier of the Whitehorse basin strata in central Tulsequah map area (NTS 104 K/11) includes interbedded fossiliferous conglomerate, sandstone, siltstone, and mudstone of the Lower to Middle Jurassic Takwahoni Formation (Laberge Group) that unconformably overlies Upper Triassic limestone of the Sinwa Formation. The refined age and provenance of several episodes of coarse clastic input into the basin show that the character of the dominant clasts in the conglomerate changes upsection. Immediately above the unconformity, breccia and conglomerate contain sedimentary clasts derived from the Sinwa Formation. Clast dominance changes to volcanic near the base of the section, plutonic (in Pliensbachian-Toarcian strata), metamorphic (in uppermost Toarcian rocks), and finally, after an interval of fine-grained sedimentation, to chert in the Middle Jurassic strata of Early Bajocian age. The uppermost chert-pebble conglomerate and the underlying black mudstone beds are tentatively placed in the Bowser Lake Group.

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.
