WebGeologists first classified minerals according to their primary chemical composition, such as iron or copper. In the mid-19th century, American geologist, mineralogist, and zoologist James Dwight Dana created a classification system that arranged minerals first by their chemistry and second by their atomic structure or symmetry of the atomic arrangement.

In crystallography, a crystal system is a set of point groups (a group of geometric symmetries with at least one fixed point). A lattice system is a set of Bravais lattices. Space groups are classified into crystal systems according to their point groups, and into lattice systems according to their Bravais lattices. Crystal … See more Crystals can be classified in three ways: lattice systems, crystal systems and crystal families. The various classifications are often confused: in particular the trigonal crystal system is often confused with the rhombohedral lattice system See more The 7 crystal systems consist of 32 crystal classes (corresponding to the 32 crystallographic point groups) as shown in the following table … See more Two-dimensional space Two dimensional space has the same number of crystal systems, crystal families, and lattice systems.
