Webstep faulting The faulting process in which separate fault blocks are downthrown systematically in one direction, forming a stepped sequence. A Dictionary of Earth Sciences WebFeb 24, 2024 · If the block of rock opposite the fault line moves to the right, it is considered a right lateral strike slip fault, or dextral. The movement at a strike-slip fault is responsible …
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.
