Fracture patterns

  1. Rotational slide (slump) in shattered rock material with no clear structure
  2.  
  3. Translational slide in rock with clearly structured discontinuities (bedding planes, cleavage foliation)
  4.  
  5. Wedge slide in rock along two intersecting discontinuity surfaces called “prisms”
  6.  
  7. Topple in solid rock with steeply sloping fracture systems
