Abstract

Faults and fractures evolve kinematically as Somigliana dislocations. As a result, displacement gradients are always present, with displacements reducing to zero at fault/fracture tips. We present a graphical method for the comparison of displacement gradients from fractures of various magnitudes and types. Displacement efficiency of a fault/fracture is defined as its ability to maximise displacement across its surface.

    Narrow mountain ridges here have a fan-shaped (broom-like) pattern, with characteristic widening from the vicinity of Žlina towards SW (Mikulov-Bratislava line) (Fig. 3A – site 10). This structure usually compensates for displacements in marginal parts of the strike-slip zone (Fig. 3D – 4) (see Higgs and Williams, 1987; Walley, 1988). Although the flower structure has been described from this region (Beidinger and Decker, 2016), it has not been linked with the horsetail structure reflected in the morphology.

    Although these are accommodated via minimum shortening estimates in line-length sections, there is a reasonable maximum projection of the hanging wall cutoff as well. If the section of interest lies close to the tip line of an emergent thrust, one could use an up-plunge projection and some model of the displacement gradient profile along a fault (Higgs and Williams, 1987; Marrett and Allmendinger, 1990; Walsh and Watterson, 1987, 1989) to determine where the now eroded hanging wall cutoff should lie. More commonly, we suspect, people will use their intuition as to the probable location of the cutoff and simply select a large uncertainty.
