NEOGENE TUSCAN SHELF-WESTERN TUSCANY EXTENSION EVIDENCES OF THE EARLY POST-COMPRESSIONAL DEPOSITS (TYRRHENIAN SEA- NORTHERN APENNINES, ITALY)
Bibliographic record
Abstract
Seismic data of the inland Volterra Basin and of the Tuscan Shelf (Northern Tyrrhenian Sea) have been analyzed to determine the tectono-sedimentary evolution of this part of the Northern Apennines from the Early Miocene (about 20 millions years ago) to the Present. The study area is characterized by a series of sedimentary basins separated by tectonic ridges. Similar environmental conditions existed both inshore and offshore as indicated by the occurrence of similar seismic units. The units are separated by major unconformities. Three main geometries characterize the basin fill of Neogene deposits: bowl-shaped (wide and small), triangular- and blanket-shaped. Small bowl-shaped basins are indicative in both the Tuscan Shelf and the Volterra Basin of pre-rift Burdigalian- Serravallian deposits (although in the Volterra Basin they could also be early Tortonian). Triangular-shaped basins are indicative of rifting and developed during late Tortonian-early Messinian in both the Tuscan Shelf and the Volterra Basin. Wide bowl-shaped basins are indicative of a post-rift regime. This occurred from the late Messinian on in the Tuscan Shelf, while during Early Pliocene the inland Volterra Basin was affected by a new period of rifting, with a well developed half-graben. From Middle Pliocene on, the post-rift phase was established over all the studied area. Blanket geometry of the Pleistocene deposits call for a fully developed post-rift phase.

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.
