Crustal Fault Zones (CFZ) as Geothermal Power Systems: A Preliminary 3D THM Model Constrained by a Multidisciplinary Approach

Figure 8

Fracture design for two samples ((a–d) and (e–h), respectively) and for smaller observation scales. Fractures underlined by red lines are marked by secondary mineral phases (mainly tourmaline and oxyde) and voids.
