Outline

• Tectonic setting
• Transform plate boundaries
• Escape structures in the hinterland of plate
  collision zones
• Transfer zones in thrust belts or normal fault
  systems
• -Development of a strike slip fault
• -Strain within a strike slip shear zone en
  echelon structures
• -Releasing bends and restraining bends
