PS Resource Assessment of Oil and Gas Plays in Paleozoic Basins of Eastern Canada*
Bibliographic record
Abstract
There are three major Paleozoic basins in eastern Canada: � Cambrian-Ordovician St. Lawrence shallow marine platform and coeval deep water facies � Silurian-Devonian shallow to deep marine Gaspé Belt � Devonian-Permian terrestrial to shallow marine Maritimes Basin The sedimentary successions are bounded by tectonically-generated unconformities- the Taconian unconformity separating Cambrian-Ordovician from Silurian-Devonian strata and the Acadian unconformity at the base of the late Devonian-Permian strata. Each basin contains unique source rock and reservoir units and specific trap types. All of the basins contain producing or discovered hydrocarbon fields but there has been no independent evaluation of their oil and gas resource potential. Over the past five years the Geological Survey of Canada and its partners have acquired new hydrocarbon systems data, in preparation for a first regional hydrocarbon play assessment of Paleozoic strata in eastern Canada. A total of 16 conventional and 2 unconventional plays have been identified. Seven conventional plays are recognized in Cambrian-Ordovician strata: � Cambrian rift sandstones � Lower Ordovician hydrothermal dolomite (HTD) � carbonate thrust slices at the Appalachian structural front

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.
