Abstract

fetched live from OpenAlex

The East Siberian Sea–Chukchi Sea Prograded Margin (ESCPM) and the Makarov Oceanic Basin (MOB) include interconnected sedimentary accumulations with gradual facies transitions that occupy a significant part of the Amerasia Basin and the adjacent Siberian Arctic continental margin. The ESCPM contains a succession of Cenozoic clinothem featuring shelf-margin progradation caused by a rapid influx of siliciclastic material from NE Asia into the adjacent Amerasia Basin, and represents a single tectono-sedimentary element (TSE) as per the volume's terminology. The MOB is a most distant part of the Arctic Ocean and is isolated from continental depositional systems. It consists of two first-order sedimentary accumulations with distinct depositional styles and provenances. The lower, Passive Margin TSE is composed of a fragment of the presumably Paleozoic–Mesozoic Barents and North Kara passive continental margin. The upper, Synoceanic TSE was formed following the separation of the continental block of the Lomonosov Ridge from the Eurasian continental margin at c. 56 Ma and during the opening of the Eurasian Basin. It includes mostly Eocene–Holocene hemipelagic and pelagic deposits and ice-rafted sediments. Each of these accumulations is characterized as a TSE, and the MOB itself is considered as a composite TSE. Assessments of petroleum potential in both elements rely on regional geological constraints, sedimentary architecture and modelling. Direct hydrocarbon indicators have been detected in seismic profiles in both the ESCPM and the MOB. In the latter, petroleum generation is likely to have begun in the Jurassic or Late Cretaceous, peaking in the Paleocene and possibly extending into the Miocene. Reservoir rocks are inferred in Cretaceous and Cenozoic strata. In the ESCPM TSE, Paleocene–middle Eocene sedimentary successions are considered to include potential source rocks, associated with main flooding surfaces and clinothem bottomset deposits.

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.
