A type of crystal with a large extension in two dimensions and a uniform thickness. A lamellar crystal is usually of a thickness in the

–

range, and it may be found individually or in aggregates. The parallel chain stems intersect the lamellar plane at an
angle between

and

.
The lamellae often have pyramidal shape owing to differences in the fold domains; as a result, one can deduce different fold planes and fold surfaces from the lamellar
morphology.
