Field guide to the geology, metamorphism and tectonics of the Foreland and Omineca belts of SW Alberta and SE British Columbia
Bibliographic record
Abstract
This field guide describes field localities that illuminate the geology, metamorphism and tectonics of the Foreland and Omineca belts of the southern Canadian Cordillera in southwestern Alberta and southeastern British Columbia. The Omineca belt contains the deformational, magmatic and metamorphic record of the Jurassic through Eocene development of this part of the Cordilleran orogen. Calgary, where the field trip starts, is situated just east of the edge of the Cordilleran deformation belt, so the geology of the famous Foreland fold and thrust belt is examined on the way to the Omineca belt. A theme of the field guide is that the structural, magmatic and metamorphic processes that occurred in the Omineca belt were intimately linked to the structural and sedimentary processes occurring at the same time in the Foreland belt. The geological domains covered by the field guide include (from east to west) the Foreland thrust and fold belt, Rocky Mountain Trench, Purcell anticlinorium, Kootenay arc, Quesnel terrane, and two Shuswap-type Cordilleran core complexes, the Valhalla complex and Grand Forks complex. The cities and towns within the geographic area covered by the field guide include (from east to west) Calgary and Banff (both in Alberta) and the following communities in British Columbia: Radium, Cranbrook, Kimberley, Creston, Riondel, Kaslo, Nelson, Salmo, Castlegar, Christina Lake and Grand Forks. The field guide covers all aspects of the geology traversed by the field trip. It comprises ten segments based on a combination of geology and geography. The field trip segments are preceded by an overview of the physiography, present-day geophysics, stratigraphy, magmatism, metamorphism, tectonics, ore deposits and geomorphology of the southern Canadian Cordillera. The field guide comprises 82 Stops, 49 Optional stops and 40 Road logs, and is illustrated with 114 figures comprising maps, diagrams, photographs and photomicrographs. Note: the field guide is large (~228 MB), so it may take some time to download.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
