The northeastern Algeria hydrothermal system: gravimetric data and structural implication

Abstract The Tell Atlas of Algeria has a huge potential for hydrothermal energy from over 240 thermal springs with temperatures up to $$98^\circ$$ 98 ∘ C in the Guelma area. most exciting region is situated northeastern part which known have hottest systems. In this work, we use high-resolution gravity study identify location and origin hot water, how it reaches surface. Gravimetric data analysis shows shapes anomalies arising due structures at different subsurface depths. calculation spectrum also showcases depths bodies causing anomalies. 3D-Euler deconvolution applied estimate preexisting tectonic (faults). These preprocessing steps assist assessing signal attenuation that impacts Bouguer anomaly map. residual used three-dimensional inversion provide density distribution model illustrates locations dominant Overall, combination these standard processing measurements surface provides new insights about sources systems Hammam Debagh Ouled Ali regions. Faults are key water infiltrating depth identified. represent pathway
