Composition of alkali picrites from the southwestern Greenland continental margin
Bibliographic record
Abstract
The Labrador Sea is a basin with oceanic crust in its deep part.Bottom morphology of the Labrador Sea is rather complicated. Data of seismic profiling in this region indicate presence of numerous submarine mountains and hills, which are dominated by volcanic rocks.Some chemical and mineral characteristics of the rocks, in particular, high concentrations of alkalis and phosphorus, and presence of high-titanium augite, ilmenite, and devitrified glass enriched in K and Na, allow us to attribute them to K-Na subalkaline picrites typical for ocean islands, seamounts, and oceanic plateaus.Rocks of the K-Na subalkaline series usually form submarine basements and subaerial volcanoes of ocean islands, seamounts, and oceanic plateaus. Thus, the suggestion on formation of the highs on the continental crust is not confirmed by petrographic data, which require a refinement of the tectonic model of the northern part of the Labrador Sea.
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.
