Abstract

fetched live from OpenAlex

Bovie Structure, a major north-south striking feature, extends over 175 km in the subsurface and subsurface of northeast British Columbia and southern Northwest Territories and defines the eastern limit of Liard Basin. Its structural history has been variously described as extensional, compressional, wrench and combinations thereof. The extensional 'Bovie Fault' found on surface maps is not supported by the seismic data. Examination of seismic and well data leads to a model in which Bovie Structure is the product of two intersecting compressional faults. The first, established as late as latest-pre-Cretaceous (and likely reactivated during the Cretaceous) was predominately vertical in motion, westward-directed and rooted in basement. The second, a product of Laramide thin-skinned deformation, was largely horizontal in effect, eastward-directed, with movement along a shallow detachment within the shales of the upper Banff Formation. The surface Bovie Anticline is seen as a block decapitated from the hanging wall of the earlier compressional uplift and carried eastward and upward during Laramide deformation.

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.

Not 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.
