Figure 6From: Possible natural fluid pathways from gravity pseudo-tomography in the geothermal fields of Northern Alsace (Upper Rhine Graben)Gravity residuals after Butterworth cut-off wavelength filtering. Gravity residuals after Butterworth low-pass (a) 20-, (b) 30-, (c) 50-, (d) 80-, (e) 100- and (f) 120-km cut-off wavelength filtering of the Bouguer anomaly with reference density 2,670 kg m−3. Gravity database from Rotstein et al. ([2006]) is used.Back to article page
