“…15). The rhombic pores are due to a dedolomitization process implying dissolution of a dolomite cement, precipitated as non-interlocking euhedral to subhedral rhombs between grains, and creating secondary pore space (Makhloufi et al, 2018). Mangenot et al (2018) dated dolomite crystals using U/Pb geochronology in cores from the Middle Jurassic oolitic reservoir located 150 km north-west of Massangis and concluded that the dolomite probably precipitated during the Early Cretaceous.…”

“…Moreover, the Late Jurassic geothermal reservoirs in the Geneva Basin (Switzerland) are controlled by dedolomitization either through calcite replacement or dissolution in granular facies (Makhloufi et al, 2018). Dedolomitization is also well-expressed in the Late Jurassic of the French and Swiss Jura Mountains (Rameil, 2008).…”

“…More recently, as the GGB became of interest for geothermal resources, a variety of geological and geophysical data are being re-interpreted (Sommaruga et al 2012;Chelle-Michou et al 2017). New rock samples are also being collected and analysed for potential-reservoir characterization purposes (Clerc et al 2015;Rusillon 2017;Makhloufi et al 2018). In addition, many geophysical data acquisition campaigns are currently being performed, including deep-reaching geoelectrics (Carrier et al 2018a), seismic-reflection lines ‡ , and gravity surveys (Carrier et al 2018b).…”

SUMMARYThe Greater Geneva Basin is one of the key targets for geothermal exploration in Switzerland. Until recently, information about the subsurface structure of this region was mostly composed of well-logs, seismic reflection lines, and gravity measurements. As part of the current effort to further reduce subsurface uncertainty, and to test passive seismic methods for exploration purposes, we performed an ambient-noise tomography of the Greater Geneva Basin. We used ∼1.5 yr of continuous data collected on a temporary seismic network composed of 28 broad-band stations deployed within and around the basin. From the vertical component of the continuous noise recordings, we computed cross-correlation functions and retrieved Rayleigh-wave group-velocity dispersion curves. We then inverted the dispersion curves to obtain 2-D group-velocity maps and proceeded to a subsequent inversion step to retrieve a large-scale 3-D shear-wave velocity model of the basin. We discuss the retrieved features of the basin in the light of local geology, previously acquired geophysical data sets, and ongoing geothermal exploration. The Greater Geneva Basin is an ideal natural laboratory to test innovative geothermal exploration methods because of the substantial geophysical data sets available for comparison. While we point out the limits of ambient-noise exploration with sparse networks and current methodology, we also discuss possible ways to develop ambient-noise tomography as an affordable and efficient subsurface exploration method.

“…The sedimentary cover, from permo-carboniferous to Quaternary (Figures 1b and 1c), is well-described in the literature (Charollais et al, 2007;Ramsay, 1963;Sommaruga et al, 2012). Suitable aquifers for the exploitation of hydrothermal resources occur in porous sandstones, karstified limestones (not considered in our model), reef or peri-reefal deposits, or dolomitized limestones (Makhloufi et al, 2018;Paolacci, 2012;Rusillon, 2017). The Permo-carboniferous clastic sediments have been suggested to be at about 4,500 m depth (Signer & Gorin, 1995).…”

Changes in precipitation rates and the accelerating melting of glaciers due to global warming will strongly affect groundwater resources, whose demand is already expected to increase for the upcoming decades due to demographic growth and urbanization (Mays, 2013). Moreover, these resources may be subject to anthropogenic contamination during well activities (Dragon, 2008;Jasechko et al., 2017). Surface-and groundwater is not only crucial for the development of our society (Velis et al., 2017) but can also play a key role in mitigating the effect of climate change through the development of renewable energies, such as hydropower and geothermal energy (Jialing et al., 2015).Despite their elevated energy potential, high-enthalpy geothermal systems remain under-developed and confined in volcanic areas. In contrast, the development of low-to medium-enthalpy geothermal systems increased significantly over the last decades in suburban regions where the energy needs are the highest (Breede et al., 2013;Olasolo et al., 2016). Additionally, several examples have shown that the energy from medium-enthalpy geothermal systems represents a valuable asset for the reduction of green-house gas emissions while supporting our growing economy (
