Effect of lithospheric thickness on the formation of high-and low-angle normal faults

  title={Effect of lithospheric thickness on the formation of high-and low-angle normal faults},
  author={Walter R Buck},
It is accepted that extension of a homogeneous brittle layer should produce high-angle normal faults. The rotation of the upper parts of such a fault to a low dip requires fault offset that is greater than the local lithospheric thickness. New model calculations indicate that a fault cutting lithosphere thicker than 10-20 km can build up only a few kilometres horizontal throw before a new fault replaces it. Such a small offset leaves the fault little rotated from its initial high dip angle. For… CONTINUE READING
