Bedrock geology of southwestern Baffin Island, Nunavut: expanding the tectonostratigraphic framework with relevance to mineral resources
Bibliographic record
Abstract
New bedrock geological mapping on southwestern Baffi n Island has highlighted the character and extent of three distinct supracrustal sequences and allowed for further subdivision and structural mapping of intervening plutonic rocks. The Lake Harbour Group outcrops predominantly south of Mingo Lake and comprises a quartzite-marble-psammite-pelite succession that can be traced southeast to its type locality near Kimmirut. Widespread exposures of carbonate-clastic rocks across Foxe Peninsula are also believed to represent Lake Harbour Group. Two stratigraphically distinct sequences, an arenaceous assemblage (Lona Bay sequence) and a gossanous mafi c-ultramafi c volcanic-bearing assemblage (Schooner Harbour sequence), are best exposed on southern Foxe Peninsula. Intervening plutonic rocks comprise mainly biotite- and/or orthopyroxene-monzogranite intrusive into the supracrustal rocks, with minor foliated to gneissic tonalite-granodiorite potentially representing depositional basement. Collectively, these rocks were deformed during at least three regional deformation events. As a result, supracrustal rocks are mainly preserved in structural basins corresponding to F1 and F2 synforms which, in turn, are separated by a broad F3 antiform.

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; a candidate call from one teacher head, not a consensus.
