2D Geoelectric Imaging of the Uneme-Nekhua Fracture Zone
Figure 5
Composite profile along TR2 indicating the locations of vertically dipping multiple low resistivity fracture paths towards the western end of the profile and multiple depressions (trenches) within the adjacent high resistivity crystalline basement to the East. (a) Inverted 2D resistivity structure along TR2, (b) conceptual geologic cross-section along traverse 2. Deep seep of surface waters within the fractures leads to very low resistivity responses. Alternately, the entire grey shaded zone could represent a continuous zone where brecciation was heterogeneous. Above the multiple fractures a broad flood plain where the stream course is less entrenched has developed.
