New insights on the Cambrian carbonate platform, Percé area, Gaspésie, Quebec
Bibliographic record
Abstract
The Percé area offers the unique occurrence of Middle Cambrian shallow-marine carbonate rocks in the Quebec Re-entrant. The Corner-of-the-Beach Formation of latest Middle Cambrian age consists of oolitic grainstone with subordinate lime mudstone and microbial thrombolite and is interpreted to record shallow-marine, carbonate plat- form margin facies. The overlying Murphy Creek Formation of early Late Cambrian (Dresbachian) age consists of a rhythmic succession of siliciclastic mudstone with minor sandstone, limestone, dolostone and two intervals of lime- stone conglomerate. The Murphy Creek Formation is interpreted as a below-wave-base slope deposit. The Cor- ner-of-the-Beach Formation is time and facies correlative with the lower part of the Port au Port Group in western Newfoundland whereas the Murphy Creek Formation is time correlative with the lowermost unit of the Cow Head Group and with the Cooks Brook Formation although, with respect to facies, correlation is more straightforward with the Cooks Brook 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.
