Cubic (crystal system)

(Redirected from Cubic body centered)

In crystallography, the cubic crystal system is the most symmetric of the 7 crystal systems. The system is composed of the three Bravais lattices whose symmetry group is that of a cube.

The three Bravais lattices that form the cubic crystal system are:

simple cubic	body-centered cubic	face-centered cubic

The point groups that fall under this crystal system are listed below, followed by their representations in international notation and Schoenflies notation, and mineral examples.

gyroidal	432		O	cuprite
diploidal	<math>\frac2m \overline{3}<math>	or <math>m3<math>	T_h	pyrite
