WebJul 5, 2024 · We call distinct combinations of symmetry, such as 222, point groups. So, the crystal in Figure 10.40 belongs to point group 222. Figure 10.36 showed a crystal that belonged to a different point group, 2/m. Point groups describe symmetry around a point in the center of a crystal, and thus they relate the points in a stereo diagram to each other ... WebIn mineralogy, crystal habit is the characteristic external shape of an individual crystal or aggregate of crystals. The habit of a crystal is dependent on its crystallographic form and growth conditions, which generally creates irregularities due to limited space in the crystallizing medium (commonly in rocks ).
