Lower to Middle Cambrian of the southern Canadian Rockies
Bibliographic record
Abstract
ABSTRACT Lower to Middle Cambrian strata, well exposed in imbricated westward-dipping thrust sheets of the southern Canadian Rockies, host a range of geologic features from famous fossil lagerstätten to economically important ore deposits. This paper describes six localities in the Front and Central ranges west of Calgary that record tectonic, sedimentologic, and biologic events during deposition of the lower to mid-Sauk Megasequence. At the Mount Yamnuska and Castle Mountain viewpoints, Middle Cambrian platformal carbonate sections are well exposed. These were preceded by thick, siliciclastic-dominated, shallow-marine deposits of the Gog Group, which form a dramatic geologic backdrop to Lake Louise. Farther west, a platform-to-basin facies transition is recorded in the vicinity of Field, British Columbia. Pb-Zn mineralization and dolomitization are evident near or at this facies transition at the Kicking Horse Mine in Yoho National Park, and on Fossil Ridge as seen from the Emerald Lake viewpoint. A hike to the famous Trilobite Beds of Mount Stephen offers opportunity for first-hand examination of the Burgess Shale biota and associated unusual mineralogic and geologic features including anomalously Mg-rich mudstone, carbonate mounds, and apparent syndepositional faulting, dilational cracks, brine seeps, and mud volcanism.

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.
