Fault-Related Controls on Upward Hydrothermal Flow: An Integrated Geological Study of the Têt Fault System, Eastern Pyrénées (France)

Figure 4

Cross-sections indicated on Figure 3. (a) Cross-section of Saint-Thomas-les-Bains and Prats-Balaguer. Hot springs emerge at the base of the Carança Range, in the Têt fault footwall, at an unfaulted gneiss-metasediments contact, close to a subsidiary brittle fault. (b) Cross-section of Vernet-les-Bains. Hot springs emerge at the base of the Canigou Range, on the CMNC ductile fault that juxtaposes metasediments in its hanging wall and gneiss in its footwall. The Têt fault crosscuts the CMNC 1 km below the surface.
