The recognition of a fossil equivalent of the active geothermal system of the Basse-Terre Island in Guadeloupe archipelago (Lesser Antilles arc) in Terre-de-Haut Island (Les Saintes archipelago) allow us to better constrain the structure, the mineralogy and the petrological characters of the deep parts of an active geothermal reservoir. First,...

Afin de décrypter l'évolution tectono-métamorphique des niveaux crustaux peu profonds de l'arc volcanique actif de l'archipel de la Guadeloupe (Petites Antilles), nous présentons de nouvelles investigations géochimiques, géochronologiques, minéralogiques et structurales du Complexe Basal, le plus ancien et le plus érodé des complexes...

The giant Jurassic-aged pockmark field of Beauvoisin developed in a 800 m wide depression for over 3.4 Ma during the Oxfordian; it formed below about 600 m water depth. It is composed of sub-sites organized in clusters and forming vertically stacked carbonate lenses encased in marls . This fine-scale study is focused on a detailed analysis of...
