Geology of the eastern Cobequid Highlands, Nova Scotia
Bibliographic record
Abstract
The eastern Cobequid Highlands, part of the Avalon terrane in mainland Nova Scotia, include Late Proterozoic to Late Paleozoic rocks. The Rockland Brook Fault divides the highlands into two blocks. To the south, Late Proterozoic rocks include granitoid gneiss and amphibolite of the Mount Thom Complex, and the Bass River Complex which includes the 734 ± 2 Ma Economy River Gneiss, platformal metasedimentary rocks of uncertain age, and the ca. 610-580 Ma Great Village River Gneiss. Coeval supracrustal rocks consist of continental tholeiitic basaltic flows and dykes and interbedded turbidite sequences. North of the Rockland Brook Fault, similarly aged arc-related volcanic and sedimentary rocks occur. Taken together, Late Neoproterozoic rocks in the eastern Cobequid Highlands may expose an oblique section across a Neoproterozoic magmatic arc. Penetrative fabrics are interpreted to reflect ductile shear-zone deformation associated with sinistral intra-arc transtension and basin development, followed by dextral transpression resulting in deformation of the basin. Late Ordovician to Early Devonian rocks comprise shallow marine sedimentary and volcanic rocks and probably correlate with the Arisaig Group to the northeast. Devonian-Carboniferous rocks comprise continental sedimentary rocks and intra-continental bimodal volcanic rocks (Fountain Lake Group) and coeval bimodal plutonic rocks (emplacement age ca. 360 Ma). Locally intense dextral transpression between the Visean and Namurian resulted in a positive flower structure, local isoclinal folds, and may be related to dextral movement on the Avalon-Meguma terrane boundary.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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; both teacher heads agree on what is shown here.
