It is similar to the arrangement in all sheet silicates. The layered structure explains why micas cleave as they do. Micas cleave into sheets because the bonds to the potassium ions are very weak compared with all bonding in other directions. 3.62 K-feldspar. Feldspars, like the K-feldspar shown, have two cleavage directions.
