Assessment of Chaves Low-Temperature CO₂-Rich Geothermal System (N-Portugal) Using an Interdisciplinary Geosciences Approach

Figure 9

Location of the VES carried out in Chaves graben and example of apparent resistivity curves acquired. Geological background adapted from [110, 111]. Lines in the filled circles represent the VES direction. Also shown are the contours of the low resistivity zones in the central part of the graben (approximate depth of 350 m) as determined from 1D interpretation of VES. Adapted from [27].
