The upper mantle of Kamchatka in isotopic-geochemical and geophysical anomalies: The role of asthenospheric diapirism
Bibliographic record
Abstract
Data of isotopic-geochemical, seismotomographic, and gravimetric studies of the mantle characteristics of the Kamchatka and Bering Sea regions are compared. It is shown that the revealed isotopicgeochemical anomalies are well verified by the geophysical materials. A hypothesis is put forward that the anomalies of the Central Kamchatka and Bering Sea regions are a consequence of the penetration of local diapirs into the lithosphere; their activity is associated with the appearance of rocks belonging to the intraplate geochemical type. The juncture region of the Kuril-Kamchatka and Komandor-Aleutian island arc systems is characterized by the higher participation of crustal material in the composition of the volcanic rocks of the mantle genesis and by a combination of manifestations of the island arc and intraplate types.

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.
