Abstract

fetched live from OpenAlex

The Frobisher Suite is a newly recognized magmatic province comprised of mafic-ultramafic sills in southern Baffin Island, Nunavut. The sills are emplaced into the metasedimentary strata of the middle Paleoproterozoic Lake Harbour Group, and vary in thickness from several meters to hundreds of meters. Based on major and trace element chemistry, the Frobisher Suite can be divided into eight geochemical groups. The major geochemical components indicate melting occurred to differing degrees within a mantle plume head, at various depths below the Meta Incognita microcontinent at ca. 1900 Ma. A number of sills formed via injections of multiple, distinct magma types, some of which were influenced by subcontinent lithospheric mantle. Disseminated sulphides are present in the sills, and in some cases, the adjacent host psammite. At this stage, the Frobisher Suite may be considered to be part of its own Large Igneous Province (LIP), termed the “Frobisher LIP.”

Full frame distilled prediction

Teacher imitation

Not 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.
