Cross-plot between porosity and resistivity and the approximate curve of Archie’s law. Cross-plot between porosity and resistivity and the approximate curve of Archie’s law for each damage zone in the hanging wall and footwall. Yellow dots: upper half of the surrounding damage zones (sdz). Yellow circles: resistivity peak in the upper half of the sdz. Yellow-lined circles: porosity increase in the upper half of the sdz. Blue dots: lower half of the sdz. Blue circles: resistivity peak in the lower half of the sdz. Blue-lined circles: porosity increase in the lower half of the sdz. Red circles: brecciated zones. The power index of the approximate curve is Archie’s m parameter.
