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...

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...

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)...

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...

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,...

Under the pressure of climate change and the transition to low-carbon energy, geothermal energy is experiencing an unprecedented worldwide craze. Investors are mobilizing, oil companies are interested in it and many companies are being created to propose solutions likely to facilitate or improve its exploitation. However, the risks associated...

Welcome to the GDR Rift Scientific Colloquium 2022 The GDR Rift is pleased to present this first scientific colloquium which took place from 22 to 24 November 2022, at the Villemanzy residence, in Lyon. This conference was open to all researchers, students, and staff involved in the GDR, wishing to address issues related to the Great African...
