Crystal system : definition of Crystal system and synonyms

Overview. The lattice system of a crystal or space group is determined by its lattice but not always by its point group. A crystal system is a class of point groups. Two point groups are placed in the same crystal system if the sets of possible lattice systems of their space groups are the same.

Likewise, although Crystal Data Determinative Ratios [5] may be used to locate similar lattices within a given crystal system, the normalized reduced cell provides the logical basis for a far more powerful and comprehensive lattice-matching technique which is crystal system independent and conceptually parallel to techniques based on matching

What are Crystal Systems and Mineral Habits?

These are examples of mineral habits or crystal systems. The isometric crystal system has three axes of the same length that intersect at 90º angles. Minerals that form in the isometric system include all garnets, diamond, fluorite, gold, lapis lazuli, pyrite, silver, sodalite, sphalerite, and spinel.
