Temperature anomaly and measurements and fault traces and dip directions. Temperature anomaly at top basement, distribution of temperature measurements and their distance to top basement, and fault traces and dip directions at top basement in the area of the 3D geological model. A temperature gradient of 39.2°C per km, corresponding to the lowest observed temperature gradient in the area, is subtracted from the temperature field at the top basement to obtain this temperature anomaly map at top basement. Temperature database from Pribnow and Schellschmidt ([2000]) and Agemar et al. ([2012]).
