Types of folds

Types of Folds

 

  1. A symmetrical foldis one in which the axial plane is vertical.
  2. An asymmetrical foldis one in which the axial plane is inclined.
  3. An overturned foldhas a highly inclined axial plane such that the strata on one limb are overturned.
  4. A recumbent foldhas an essentially horizontal axial plane.
  5. An isoclinal foldhas limbs that are essentially parallel to each other and thus approximately parallel to the axial plane.
