Name:
From the Greek κύλιυδροσ, a roll, in allusion to the typical cylindrical habit of the mineral.
Cylindrite Group.
There is a relation between the cylindrical morphology and crystal structure. The latter is composite and characterizes in incommensurate modulations. There are two types of sheets, a pseudohexagonal one and a pseudotetragonal one, both with distinct lattice parameters. Crystals' core has different structure than its outer zone: the b and c axes of the two sheets are nearly parallel, but the more far from the core the more clear sheet rotation is observed. Layer curving is one of the ways of an accomodation of the dimensional sheet misfit by a cylindrite crystal.
