Structure of the South-Eastern Nechako Basin, British Columbia: Results of Seismic Interpretation and First-Arrival Tomographic Inversion
Bibliographic record
Abstract
Summary Reinterpretation of Canadian Hunter seismic reflection profiles provides new insight into the complex structure, stratigraphy and tectonic history of the south-eastern Nechako Basin. The basin, which contains predominantly Mesozoic sedimentary and volcanic rocks, is overlain by Eocene and Neogene volcanic rocks and Pleistocene glacial deposits that mask the underlying geology. New results reveal details of how Cretaceous sedimentary and volcanic rocks, deformed during preEocene transpression, were re-activated and cut by NW-SE trending strike-slip faults related to Eocene transtension. First-arrival tomographic models provide new information on the structure and velocity of the near-surface volcanic rocks. The focussing of model rays allows for estimation of the thickness of the Endako Group in the vicinity of well b-82-C, and may elsewhere provide information on the thickness of the Neogene and Eocene volcanic rocks.
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.
