Sequence stratigraphy and sedimentology of the Paleoproterozoic Baker Lake Group in the Baker Lake Basin, Thirty Mile Lake, Nunavut
Bibliographic record
Abstract
In the Thirty Mile Lake area of the Baker Lake Basin, lithofacies assemblages representing alluvial fan, gravel- and sand-bed braided stream, lacustrine, and ephemeral lacustrine depositional environments characterize the lower part of the ca. 1.83 Ga Baker Lake Group. Five depositional sequences that unconformably overlie Archean basement are identified from this interval. These depositional sequences record the following accommodation cycles: initial base-level drop, subsequent base-level rise, increase in gradient as accommodation increased, decrease in gradient as accommodation space filled, and continued base-level rise. Sequences stack in a retrogradational pattern indicating that, for the interval recorded, accommodation space creation exceeded sediment flux and the basin was underfilled. Subsidence probably was due mainly to normal faulting on the southern margin of the basin. Alkalic volcanism occurred throughout the early depositional history of the Baker Lake Basin.
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.
