Fig. 1From: How do the geological and geophysical signatures of permeable fractures in granitic basement evolve after long periods of natural circulation? Insights from the Rittershoffen geothermal wells (France)Location of the Rittershoffen geothermal site. a Simplified geological and structural map of the Rittershoffen and Soultz-sous-Forêts (SsF) area. The isotherms at the top of the basement are from Baillieux et al. (2014). b Geological cross section through the Rittershoffen and Soultz-sous-Forêts geothermal sites with the Rittershoffen well trajectories, after the GeOrg Team (2017). The dashed lines are schematic trajectories of the GRT-1 (blue) and GRT-2 (red) geothermal wells (Vidal et al. 2018)Back to article page
