The eastern extent of the Risky Formation (Ediacaran), Mackenzie Mountains, Northwest Territories
Bibliographic record
Abstract
Newly documented exposures of dolostone, sandy dolostone, and quartz arenite in the Natla structural panel, western Wrigley Lake map area (NTS 95-M; Mackenzie Mountains, Northwest Territories) are assigned to the Ediacaran Risky Formation. Similarities in lithology and stratigraphic succession with the type area of the formation (Sekwi Brook structural panel, Mackenzie Mountains) support the assignment. The newly recognized occurrence of Risky Formation is within an interval previously mapped as Backbone Ranges Formation and implies that the base of the Cambrian is much higher within that unit than is suggested by previous correlations. The Risky Formation forms an eastward-thinning tongue within the Backbone Ranges Formation and may extend as far east as the hanging wall of the Plateau Fault. Karst breccia within the Risky Formation hosts base-metal mineralization in the type area of the unit and in the Wernecke Mountains. Thus, there may be limited exploration potential in the eastward extension of the Risky Formation.
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.
