We present integrated structural, petrological, mineralogical and geochemical investigations conducted on an ex-humed hydrothermal system identified in Terre-de-Haut Island (Guadeloupe archipelago). This work demon-strates, for the first time, the occurrence of ductile shear zones, marked by the development of spaced schistosity planes...

This study takes part in the GEOTREF project (high enthalpy geothermal energy in fractured reservoirs), supported by the French government program "Investments for the future". The program focuses on the exploration of geothermal resource in the Lesser Antilles volcanic arc. An exclusive license has been issued in the Vieux-Habitants area...

This work is implemented through the GEOTREF program which benefits from the support of both the ADEME and the French public funds "Investments for the future". The program focuses on the exploration for geothermal resources in Guadeloupe, Lesser Antilles, where a geothermal power plant is in production since 1986 (Bouillante, Basse Terre). In...

The GEOTREF project (high enthalpy geothermal energy in fractured reservoirs), supported by the French government program, "Investissements d'avenir" develops a sustainable geothermal resource in the Vieux Habitants area, 8-km south of the currently exploited Bouillante geothermal field. The Basse Terre Island is a recent volcanic arc (< 3 Myr)...

13 The GEOTREF project aims at developing high enthalpy geothermal energy in fractured reservoirs. It 14 focuses on active volcanic islands and especially on the Basse-Terre Island (Guadeloupe archipelago). As part 15 of this project we measured several petrophysical properties to better understand how fluids flow in the 16 hydrothermal system,...
