Week 4: Growth Faults and Listric Faults

• Listric Faults

  • Listric faults are normal faults with variable dip across the fault face, they are typically steeper near the surface and shallower deeper down
  • Listric faults are common in sedimentary basins where their characteristics are seen in growth faults
• Growth Faults

  • Growth faults are faults that are active during the period of sedimentary deposition
  • They are normal faults and are commonly seen in extensional sedimentary basins
  • This leads to varying thicknesses of layers, with a tendency to be wedged shaped
