The Nuussuaq Basin exposes Cretaceous and Paleocene siliciclastic strata, referred to as the Nuussuaq Group, overlain by volcanic rocks, mainly of Paleocene age, referred to as the West Greenland Basalt Group. Regional seismic studies indicate that the Cretaceous strata of the Nuussuaq Basin may be correlated to the Appat and Kangeq seismic sequences in the offshore basins.The present paper re-investigates five profiles, trending roughly east-west, from northern Disko to southern Svartenhuk Halvø, which exemplify the litho-and biostratigraphy, with a focus on the pre-Campanian deposits. The oldest exposed strata belong to the non-marine Kome Formation of possible Albian age. Dinoflagellate cysts that indicate brackish water conditions characterize the Albian and early Cenomanian, whereas marine dinoflagellate cysts occur in the latest Cenomanian, and in younger deposits. The dating of the Nuussuaq Group is based mostly on palynology, supported by scarce ammonites. A new, refined palynoevent stratigraphy is established, based on the study of many new and older sections. The new palynoevent stratigraphy allows a better correlation between widely spaced onshore sections and offshore successions, and provides an improved basis for paleogeographical interpretations.

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.
