lamellar crystal sector

https://doi.org/10.1351/goldbook.14250
Portion of a lamellar crystal, often bounded by a well-defined crystal face.
Notes:
  1. The term generally applies to solution-crystallized lamellar crystals. Sectors are described using the indexing of the crystal face bounding it.
  2. The fold plane prevailing in a sector is normally assumed to correspond to the crystal face bounding the sector.
  3. For some crystal morphologies, the fold surfaces of a sector make an angular discontinuity with the fold surfaces of contiguous sectors.
  4. Lamellar crystal sectors in folded-chain crystals correspond to fold domains.
