Kimberlite and Diamond Indicator Minerals in Northeast British Columbia, Canada – A Reconnaissance Survey
Bibliographic record
Abstract
Northeast British Columbia is underlain by Precambrian basement that belongs to the North American craton (Figure 1). It has diamond exploration potential, particularly if the modified "diamondiferous mantle root model " is considered (Simandl, 2004). This heavy mineral reconnaissance project expands on an earlier study, which was restricted to kimberlite indicator minerals (KIMs) present in Late Pleistocene glaciofluvial sands and gravels sampled in the Fort Nelson region (Levson et al., 2004; Simandl et al., 2005). A variety of media were sampled and tested during this study, including bedrock and regolith of partially consolidated conglomerates of the Dunvegan Formation, active river/stream sediments, and glaciofluvial or glaciolacustrine deposits. Of the 58 samples processed, 38 contain KIMs, such as purple
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.
