The Transylvanian basin, transfer zone between coeval extending and contracting regions: Inferences on the relative importance of slab pull and rift push in arc–back arc systems
Bibliographic record
Abstract
Structural analysis and paleostress fault slip inversion of the Transylvanian basin and its border regions with the surrounding East and South Carpathians and the Pannonian basin (e.g., the Apuseni Mountains) reveal at least two distinct tectonic phases for the Neogene evolution for the eastern part of the Pannonian basin system. Our main focus is on the role of the Transylvanian basin and its border regions in the Neogene as a transition zone between the extending Pannonian basin and the converging East and South Carpathians. The results provide constraints on the mechanisms responsible for as well the formation of the Transylvanian basin itself as on the relation between the basin‐formational processes operating in the Pannonian basin and the contractional history of the East and South Carpathian mountain belt. In the middle Miocene (17–14/12 Myr) the Transylvanian basin underwent E‐W extension coeval with the first and major phase of overall E‐W extension affecting the Pannonian basin and with submarine accretionary wedge tectonics in the East Carpathian arc. In the late Miocene to early Pliocene (12–8/6 Myr) the Transylvanian basin experienced a strong pulse of E‐W oriented shortening coeval with the climax of compression in the East Carpathians and a second rift phase affecting the Pannonian basin. Continued contractional deformation affected the Transylvanian basin during the Pliocene and Pleistocene with compression directions shifting to ESE‐WNW directions.

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.
