Abstract. Physical factors likely to affect the genesis of the various fault rocks—frictional properties, temperature, effective stress normal to the fault and differential stress—are examined in relation to the energy budget of fault zones, the main velocity modes of faulting and the type of faulting, whether thrust, wrench, or normal.
1 de ene. de 1977 · Sibson (1977) showed that vertical strike-slip faults lying at 22° to 32° to the maximum compression, which corresponds to 58°-72° and 292°-302°-trending faults in the study area, are ...

The most influential classification of fault rocks (Fig. 1a) is that of Sibson (1977), derived from precursors by Spry (1969) and 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.
of geothermal springs and fumaroles (Sanchez et al., 2013; Sibson, 1996; Tardani et al., 2016; Veloso et al., 2019), and the location, magnitude, frequency, and timing of crustal seismicity (Cox, 2016). Geophysical studies can image these active structural and hydromagmatic systems in order to map their architecture as a function of depth.
28 de dic. de 2020 · The paper “Fault Rocks and Fault Mechanisms” by R. H. Sibson (1977), was one of the first studies that established major connections between the rocks that form in faults, and their conditions and mechanics during formation at crustal scale.
