Stratogenèse associée à la dynamique des coulées à front pierreux en milieu alpin, La Mortice, Alpes méridionales, France
Bibliographic record
Abstract
L'étude des dépôts de pente nappant les versants est et nord-ouest de La Mortice (3170 m, Alpes méridionales, France) met en évidence le rôle de la dynamique des coulées de solifluxion à front pierreux dans le développement d'une stratification. Au sein des coulées, la cryoexpulsion et le lavage produisent la différenciation d'un front caillouteux associé à un pavage superficiel et d'un niveau riche en matrice. Ce dernier progresse par cryoreptation et ensevelit le front pierreux au fur et à mesure de sa constitution, pour former ainsi un lit grossier enterré à structure ouverte. La cryoturbation et des transferts de matière hors du système constitué par la coulée (éluviation de la matrice, expulsion et transit des blocs en surface) s'opèrent pendant le dépôt et perturbent la stratogénèse. La comparaison des dépôts provenant des deux versants de La Mortice ainsi que des exemples déjà connus dans les Andes montre que la stratification est d'autant mieux exprimée que le nombre de cycles gel-dégel annuels est important et que la profondeur d'engel est faible.

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.
