Infilled fracture: If the infilling is a weak clay or fault gouge, the friction angle (Cl) is likely to be low, but there may be some cohesion if the infilling is undisturbed. Alternatively, if the infilling is a strong calcite, for example, which produces a healed surface, the cohesive strength may be significant (see Section 2.3). 2.
