The axial plane of a fold is the surface

  • A.lying at right angles to the fold axis
  • B.along which the limbs have slipped
  • C.of maximum curvature in one bed only
  • D.containing the hinge lines of successive beds

Answer: D

Correct answer: containing the hinge lines of successive beds

Each folded bed has a hinge line where its curvature is greatest, and the surface joining those hinge lines through the whole folded sequence is the axial plane. Its orientation classifies the fold: vertical for a symmetrical fold, inclined for an asymmetrical or overturned one, horizontal for a recumbent one. It is not perpendicular to the axis - the axis lies within it.
