A palynological investigation of the till succession from the Weyburn oilfield, Weyburn, Saskatchewan, Canada
Bibliographic record
Abstract
A palynological investigation of twenty-four samples from four boreholes drilled into the till on \nthe Weyburn oilfield was undertaken. All samples produced abundant and well-preserved \npalynomorphs of Devonian, Carboniferous, Late Cretaceous and Quaternary age. The relative \nproportions of these elements proved relatively similar throughout; Late Cretaceous \ndinoflagellate cysts and pollen grains are the dominant elements, indicating that the principal \nsedimentary input to the till is from Upper Cretaceous (Campanian-Maastrichtian) units. \nDevonian, Carboniferous and Quaternary grains are consistently subordinate. The Devonian \npalynomorphs are from Manitoba to the north-east and the Late Cretaceous palynomorphs \nappear to be derived locally. The abundance of palynomorphs is testament to consistently high \nlevels of sedimentary rock input to the till successions. The relative homogeneity of the kerogen \nand palynofloras from the till samples has not allowed the palynological differentiation of units A and B. The four samples from the supposed ‘bedrock clay’ yielded similar palynofloras. \nThese samples have high organic productivities, the highest levels of Devonian input, no \nCarboniferous spores, the lowest Cretaceous abundances, relatively high levels of both \nQuaternary taxa and non-age diagnostic palynomorphs. Because the palynomorph associations \nare so heterogenous and similar to the overlying unequivocal till the ‘bedrock clay’ is probably \nglaciogenic in origin.

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; both teacher heads agree on what is shown here.
