Cubic (crystal system)
|
|
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 |
| 
| Missing image Cubic,_face-centered.png Cubic, face-centered |
BCC - Body-centered cubic.
FCC - 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.
| name | international | Schoenflies | example | |
| hexoctahedral | <math>\frac4m\overline{3}\frac2m<math> | or <math>m3m<math> | Oh | galena |
| gyroidal | 432 | O | cuprite | |
| diploidal | <math>\frac2m \overline{3}<math> | or <math>m3<math> | Th | pyrite |
| tetrahedral | <math>\overline{4}3m<math> | Td | sphalerite | |
| tetartohedral | 23 | T | ||
