Comparison and interpretation of clay mineral repartitions of active- and paleo-geothermal systems of Bouillante and Terre-de-Haut, respectively. a Map of the Guadeloupe archipelago with locations of the active Bouillante geothermal system, and of the paleo-geothermal system of Terre-de-Haut. b Schematic 2-D view of the repartition of the clay minerals in Bouillante geothermal system [modified after Bouchot et al. (2010)]; c 2-D representation of the clay mineral distribution in the exhumed paleo-geothermal system of Terre-de-Haut associated to the paleo-isotherms deduced from Bouillante active geothermal system (Bouchot et al. 2010). d 3-D interpretation of the geothermal systems in Guadeloupe, with their clay mineral distribution. Black lines correspond to hypothetic faults.
