Palynological assemblage from Aptian/Albian from the Sergipe Basin: paleoenvironmental reconstruction
Bibliographic record
Abstract
Palynological analysis was carried out on 272 core samples from two wells (GTP-17-SE and GTP-24-SE) in the Sergipe basin with the aim of reconstruction the paleoenvironment of the upper Aptianmiddle Albian interval.The Paleoecological studies based on the abundance and composition of all palynomorph genera revealed four assemblages.The stratigraphic distribution of these assemblages allowed the definition of seven ecophases.The palynological assemblage reflects the paleoenvironmental history of the succession that is marked by the progressive late Aptian-middle Albian transgression into the area.The data, in particular the ecophases, confirm that the change from a brackish lagoon to open marine environment was controlled by sealevel during deposition of Muribeca Formation, and dominantly by a progressive sea-level rise during the beginning of the Riachuelo Formation deposition.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
