Position of Quaternary Lower Boundary of the Arctic Chukotka According to Diatom Analysis
Bibliographic record
Abstract
The International Union of Geological Sciences proposed to establish the lower boundary of the Quarter at a level of 2.58 million years ago (Norway, 2009), and this was then adopted on the proposal of the International Commission on Stratigraphy. This decision caused heated discussion, requiring substantiation of the new position of the stratigraphic boundary and inclusion of the Gelazian stage of the Pliocene in the Quarter. This positioning could significantly affect the development of the structure and hierarchy of stratigraphic units of the Quarter. The issues of the criteria for drawing a new border, their unification in various geographic regions and regional geological stratotypes are principally considered. This paper examines the queries of the criteria and eligibility of a new Neogene-Quaternary boundary in the Upper Cenozoic continental sediments of the Chukotka using data derived from diatoms.

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.
