Using stress deflections to identify slip events in fault systems

Deciphering neotectonics from river profile analysis in the karst Jura Mountains (northern Alpine foreland)

“…Knickpoint 3 is localized at the junction between the N-S Pontarlier sinistral fault and the NE-SW fold axis. However, the left lateral strike-slip fault of Pontarlier cuts the fold axis at this location (Laubscher 1992;Homberg et al 2004), and our field observations are in agreement with a purely horizontal displacement. Although displacements caused by pure strike slip faults theoretically cannot trigger disturbances along river longitudinal profiles, these fault zones can act as preferential drainage patterns potentially creating deep canyons (e.g., the narrow deep valley of the Doubs River, south of Pontarlier, Fig.…”

Kinematic development and paleostress analysis of the Denizli Basin (Western Turkey): implications of spatial variation of relative paleostress magnitudes and orientations

“…Over the last three decades, paleostress inversion techniques have been applied to various tectonic settings and have proved to be empirically valid and successful, despite the fact that there are certain limitations (Pollard et al, 1993;Nemcok and Lisle, 1997;Twiss and Unruh, 1998). Furthermore, paleostress inversion studies are also used to determine the effect of past slip events along active faults by making use of deflections in the orientations of the stress axes to recognize stress perturbations near the major faults (Homberg et al, 1997, Homberg et al, 2004. Most of the analytical methods apply the Wallace (1951) and Bott (1959) assumption, which states that slip occurs parallel to the maximum resolved shear stress on a pre-existing and/or newly formed fault plane.…”

Paleostress regimes from brittle structures of the Karakoram–Kohistan Suture Zone and surrounding areas of NW Pakistan

“…1). This is interpreted as the influence of active slip on these faults that tend to release shear stress within their plane (Anderson, 1951;Chinnery, 1963) as recognized from outcrop (Rispoli, 1981) to regional scale (Homberg et al, 2004). This local influence is superimposed on regional trends that we discuss now.…”
