Mineral Crystal Systems Identification Tips and Hints
Isometric • Also called the Cubic Crystal System • Examples: Halite Magnetite Pyrite
Hexagonal Six-sided prisms When you look at the crystal on-end, the cross section is a hexagon. Examples: Apatite Beryl Quartz Calcite
Tetragonal Similar to cubic crystals Longer along one axis than the other Forms double pyramids and prisms. Example: Zircon
Orthorombic These crystals result by stretching a cubic lattice structure. A rectangular prism with a rectangular base results. Aragonite
Monoclinic Rectangular Prism Parallelogram base Orthoclase
Triclinic 3 axes All of axes are unequal in length None of the axes are right angles to each other.
