Abstract

The gravity compilation over the low density evaporite Boehner in their early 1980s mapping and Boehner's major 1986 (salt) deposits in the Shubenacadie-Stewiacke Carboniferous Salt and Potash Resources in Nova Scotia, Bulletin No. 5, sedimentary subbasin of south central Nova Scotia has been provided the necessary background infonnation. The gravity expanded to cover the area 45°00' to 45°15'N and 63°15' to models have led to some significantly different interpretations .63°36'W at a standardized scale of I :35 000. The compilation from the earlier work. a) The Stewiacke Formation (salt) is now involves almost 1975 historic and modem gravity continuous along the axis of the basin but does not appear to stations. These data have now been contoured with the extend northwest of the Otter Brook and Roulston Comer faults Surfer contouring package to produce a more accurate or southeast of the Milford Station-Meadowvale fault system. It contoured representation of the gravity data. The addition of may be tenninated by a steeply dipping fault to the southwest. b) 235 stations to the west has allowed better definition of the To the northwest of the Otter Brook and Roulston Comer faults area of more positive Bouguer gravity anomaly values to the the Horton Group sedimentary rocks become much thinner. c) northwest and to extend the main negative anomaly to the The Admiral Rock Anticline is a salt-cored anticline and there is southwest.

Not 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.
