LITHOSTRATIGRAPHY AND STRUCTURE OF THE HUMBER ARM ALLOCHTHON IN THE TYPE AREA, BAY OF ISLANDS, NEWFOUNDLAND
Bibliographic record
Abstract
The type area of the Humber Arm Allochthon contains continental margin sedimentary units of the Humber Arm Supergroup. Clastic units of the Blow Me Down Brook, Summerside, and Irishtown formations are assigned to the Curling Group. Overlying shale and carbonate sediments of the Cooks Brook and Middle Arm Point formations comprise the Northern Head group. At the top of the succession, the Eagle Island formation records the early stages of Appalachian tectonism. Early (D1) structures in the allochthon include a pervasive, generally bed-parallel foliation or fissility, and abundant boudinage structures generated by brittle fracturing. F1 folds display a variety of relationships with the S1 foliation. In more highly deformed units, bedding cannot be traced through outcrops, and the S1 foliation has a scaly, anastomosing character. Disruption of bedding is measured by a disruption index, on a scale of 1 to 5. Melange is characterized by the mixing of rocks from different formations, in addition to intense disruption of stratification. D1 structures are overprinted by S2 cleavage that crenulates the S1 cleavage in the west, but which becomes generally penetrative in the east. Upright F2 folds are widespread. The S3 and S4 crenulation cleavages are only locally developed. Map scale F3 folding is responsible for distortion of F2 hinges producing domes and basins in the outcrop pattern.
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.
