Predicted paleoceanographic reconstructions for the Mid-Cretaceous Seaway in the Cenomanian and some end-member calibration points: implications for regional natural carbon sequestration
Bibliographic record
Abstract
ABSTRACT Getech Globe 2022 paleogeographic maps provide a useful starting point to predict processes that natural carbon sequestered from the biosphere into the lithosphere. The predicted facies distributions (sand, mud, and carbonate from basin margin to center) are broadly consistent with end-member calibration points of rocks collected from different locations in the basin. For instance, siliciclastic muddy facies were predicted within the fore deep of Western Interior Basin on a storm dominated ramp, in Alberta (Canada) where sediment was being supplied by fluvial systems draining a widespread floodplain. While limestone (calcareous biogenic detritus rich mudstones) deposition was predicted in regions deposited on the fore bulge in Colorado (USA), in settings bypassed by clastic sediment supply. Regions of predicted upwelling are located in relatively close proximity to the organic carbon carbon-rich facies of the Eagle Ford, in West Texas and to a lesser extent in the fore deep of Alberta. Across the basin the predicted shallow bathymetries are also consistent with the widespread evidence of deposition within storm wave base. Reduced rates of sedimentation, and availability of both reductants and oxidants resulted in respiratory processes being responsible for significant organic carbon degradation across the fore bulge and precipitation of widespread pre-compaction carbonate cements close to the sediment–water interface in the basin center. While carbon sequestration was dominated by organic carbon burial over much of the muddy reaches within the basin, a carbonate and organic carbon path through the carbon cycle is predicted in basin center. The predictions that the water column was neither salinity nor temperature stratified is backed up by the observation of rock fabrics that contain little evidence of classic suspensionsettling fabric motifs (such as varves and undisturbed lamination).

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.
