What is the difference between crenulation lineations and intersection lineations?
What will be an ideal response?
Ans: A crenulation lineation is made up by small crenulations or microfolds and therefore reflect layer-parallel shortening. An intersection lineation can be the intersection between any two sets of planar structures, and does not have to have this relation to the strain ellipsoid.
