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 550 nm range, and it may be found individually or in aggregates. The parallel chain stems intersect the lamellar plane at an angle between 45 and 90. 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.
