Abstract : The recent surface exploration data acquired in Martinique led to a revisit of the conceptual models of three geothermal systems in active volcanic arc context: Petite Anse in the Southwest of the island, Lamentin in the center, Montagne Pelée in the North. These three explored systems are compared with each other and with the developed Bouillante geothermal field in Guadeloupe (15 MWe). From parameters, such as reservoir temperature, duration of the geothermal system using fossils events, age and duration of magmatism, degree of equilibrium of geothermal fluid, we propose a continuum model of geothermal system including three successive stages: prograde, peak and retrograde.
