Abstract

fetched live from OpenAlex

La technique K-Ar Cassignol-Gillot nous a permis de définir les limites temporelles du volcanisme effusif sub-aérien de l île de Basse Terre, Guadeloupe, et de préciser les périodes d activité des quatre massifs de l île. Le Complexe Basal [2,79+-0,04 - 2,68+-0,04 Ma], la Chaîne Septentrionale [1,81+-0,03 - 1,15+-0,02 Ma], la Chaîne Axiale [1023+-25 - 435+-8 ka], le complexe de Grande-Découverte (GD) [205+-28 - actuel] illustrent la migration du volcanisme à Basse Terre depuis 3 Ma suivant une direction principale N-S et une vitesse de 20 km/Ma. L extraction des magmas serait contrôlée par les systèmes de graben E-W et failles normales en échelon NW-SE affectant la Guadeloupe. Les taux d extrusion calculés sur la base d observations et modélisations morphologiques vont de 1,4 10-5 à 4,5 10-4 km3/yr. Au sud du volcan de GD, les diverses phases d'activité effusive du complexe de Trois-Rivières-Madeleine montrent une contemporanéité avec celles du volcan de GD. Les coulées de Trois-Rivières (87+-5 ka) puis l alignement E-W Madeleine-Le Palmiste (70 à 45 ka) datent une phase de propagation du rift de Marie-Galante. Des coulées <15 ka dans l'environnement du dôme de la Madeleine permettent d étendre à l extrême sud de l île la zone d activité volcanique Holocène. L aléa volcanique n est plus restreint au Massif de Soufrière-GD mais doit être étendu en son sud au massif de Madeleine-Trois-Rivières. Des effondrements de flanc majeurs ont été datés sur les îles de Basse Terre (640 ka, 550 ka), Dominique (100 ka), Martinique (330 ka) et Sainte-Lucie (100 ka). Une relation causale entre la récurrence de ces phénomènes catastrophiques et les changements climatiques globaux est proposée.

Not 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.
