Answer: The zone of maximum curvature of the surface in a fold.
Card 3
Question: What are the limbs of a fold?
Answer: The areas between the hinges of a fold.
Card 4
Question: What is the axial plane of a fold?
Answer: The imaginary plane equidistant from each limb that bisects the angle between them.
Card 5
Question: What is the fold axis?
Answer: The line where the axial plane cuts the hinge zone of the fold.
Card 6
