Classification of fault breccias and related fault rocks ...

2. Available non-genetic classifications. The most influential classification of fault rocks (Fig. 1a) is that of Sibson (Reference Sibson 1977), derived from precursors by Spry (Reference Spry 1969) and Higgins (Reference Higgins 1971).This classification uses primary cohesion (that is, cohesion at the time of fault movement) and the presence of foliation as the main discriminants.
