The Lower Jurassic at Peniche (Lusitanian Basin): recent advances in Stratigraphy and Sedimentary Geology
Bibliographic record
Abstract
In the Lusitanian Basin (west-central Portugal), the Lower Jurassic deposits are well exposed and are dominated by carbonates.Framed by a beautiful and unique Atlantic coastal landscape, the Peniche Peninsula shows the most important and continuous section of the Lower Jurassic in Portugal, providing a record of around 20 Myr of Portuguese geological history (Sinemurian to Toarcian).The importance of this site is testified by the large number of recent research studies in different domains of sedimentary geology and stratigraphy.This field-trip focuses on three main topics of international scientific interest: a) the Sinemurian and Pliensbachian organic-rich deposits, one of the chief intervals of hydrocarbon source potential in the western Iberian margin; b) the Pliensbachian-Toarcian boundary at Ponta do Trovão, which has been ratified as the Toarcian Global Boundary Stratotype Section and Point (GSSP) a ; and c) the early Toarcian oceanic anoxic event recorded at Abalo beach.

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.
