Gypsum is a mineral with a monoclinic crystal system. Its crystals typically form as prismatic or tabular monoclinic shapes.
Rhombohedral.
Monoclinic.
Dolomite typically exhibits three cleavage planes that intersect at approximately 90 degrees, resulting in rhombohedral cleavage.
Crystal systems differ based on the arrangement of atoms within the crystal lattice. There are seven crystal systems: cubic, tetragonal, orthorhombic, monoclinic, triclinic, hexagonal, and rhombohedral. Each system has unique geometric properties that define the shape of the crystals formed.
Gypsum and orthoclase feldspar are in the monoclinic crystal system.
