Abstract

fetched live from OpenAlex

Abstract Variations in microfaunal abundance are a useful tool in recognizing basin evolutionary stages. The Western Black Sea basin, situated near a continental passive margin, has three evolutionary phases: flysch, filling, and shelf sedimentation. Flysch sediments accumulated after basin rifting and contain rare and sporadic microfossils. During the filling phase, mostly turbidite sediments accumulated. Their microfossil record shows mixed, rather poor assemblages in periods with increased terrigenous input, but the assemblages are rich in hemipelagic sediments at the tops of turbidite sequences. The most diverse and abundant assemblages occur in sediments of the shelf sedimentation phase. During a basin evolutionary stage, microfaunal abundance shows a gradual upward increase, reaching highest values at the top. A tentative correlation with the supercycles of the Haq et al. (1988) chart is made. This correlation shows that a microfaunal abundance peak is situated in the lower proximity of a supercycle top in the Haq et al. (1988) chart.

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.
