A summary of the Paleozoic biostratigraphy and reexamination of palynology samples from the 9590 to 10 000 ft. (2923.03048.0 m) interval of the Gannet O-54 well, Grand Banks of Newfoundland
Bibliographic record
Abstract
Five unoxidized palynological (kerogen) slides from the lowermost section of the Gannet O-54 well (part of the Geological Survey of Canada - Atlantic's archived slide collection) were re-analyzed with the hope of providing refined ages for this mainly indeterminate interval: slides P3580-07 (9590'/2923.0 m), P3581-07 (9690'/2953.5 m), P3582-07 (9790'/2984.0 m), P3583-07 (9890'/3014.5 m), and P3584-07 (10 000'/3048.0 m). Thermal alteration indices (TAIs) were also measured where possible. Three of the slides are barren (P3581-07, P3583-07, and P3584-07). One slide (P3582-07) contains two spores: Middle to Late Devonian Ancyrospora sp. with a TAI value of 6+ and an indeterminate spore with a TAI value of 5+. Both spores are interpreted as caved and thus not useful in determining age. Only one slide, P3580-07 (9590'/2923.0 m), yields in situ, identifiable spores, indicating a Middle to Late Devonian age, which is consistent with previously published palynological data for Gannet O-54.
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.
