The "Subsurface: a Common Good" research program addresses five regional worksites, each concerned by specific types of subsurface uses and resources.
Chantiers régionaux PEPR Sous-sol
  • The Rhine Graben and its deep geothermal potential;
  • The centre of the Paris Basin, which represents the majority of the socio-economic challenges that exist in terms of managing the urban subsurface;
  • French Guiana, which has an extraordinary yet fragile ecosystem as well as a rich but little-known subsurface;
  • The Aquitaine basin, for the storage of emerging geo-resources and energy uses;
  • The Massif Central, for studying the geological and social conditions that could enable the region to contribute to current transitions.

Deep geothermal energy in the Rhine Graben
Within the context of the energy transition, developing deep geothermal energy in this Graben (which is a genuine natural research laboratory) is a major priority, since it will enable its significan…

AquiBEAT: Geology of the Aquitaine Basin for the energy transition
The AquiBEAT project of the "Subsurface: a Common Asset" PEPR aims to create a research community devoted to the subject of energy transition in the Aquitaine Basin, in order to improve geological kn…
Commune de Chirols - Massif Central
Massif Central project to study the geological and social conditions under which the region can contribute to current transitions
This project aims to identify and understand the geological and societal issues – whether assets or obstacles – that will determine the future use of the subsurface at various sites in the French Mas…
Un filon pegmatitique dans la région de Kourou
French Guiana (GOYAVES)
French Guiana's subsoil has often been approached from a purely extractive angle, particularly mining, making it a politicized and controversial subject. The GOYAVES project aims to break out of this…
