Right lateral motion of a strike-slip fault at a right stepover (or overstep) gives rise to extensional bends characterised by zones of subsidence, local normal faults, and pull-apart basins. On extensional duplexes, normal faults will accommodate the vertical motion, creating negative relief. See more Strike-slip tectonics or wrench tectonics is the type of tectonics that is dominated by lateral (horizontal) movements within the Earth's crust (and lithosphere). Where a zone of strike-slip tectonics forms the boundary between two See more Areas of strike-slip tectonics are associated with: Oceanic transform boundaries Mid-ocean ridges are broken into segments offset … See more Stepovers When strike-slip fault zones develop, they typically form as several separate fault segments that are offset from each other. The areas between the ends of adjacent segments are known as stepovers. In the case of a dextral … See more • Strike-slip tectonics course notes from Jyr-ChingHu, Department of Geosciences, National Taiwan University See more WebWhen a strike-slip faultis offset along strike such as to create a gap e.g. a left-stepping bend on a sinistral fault, a zone of extension or transtensionis generated. Such bends are known as releasing bendsor extensional stepoversand often form pull-apart basinsor rhombochasms.

WebFeb 17, 2012 · On Tesla Road several right-stepping fractures, one of which showed 1.5 mm of left-lateral strike slip, lie on or close tp previously mapped strands of the Las Positas fault zone. The evidence at these two localities indicates that tectonic surface displacement occurred along at least 1.1 km of the Las Positas fault zone.

WebOct 1, 2013 · This supports the interpretation of Putirka and Busby (2007) that the range-front faults formed a releasing right step that controlled the siting of the Little Walker caldera; however, Putirka and Busby (2007) did not realize that the right-stepping fault system on the range front at Sonora Pass forms only a small part (about a fourth) of a ...
