Mineral Colour Plates are small thumbnail images of minerals, as well as synthetic compounds and chemical elements, with articles that can be found in the MIROFOSS database. The following table shows all of the TRICLINIC CRYSTAL minerals found in MIROFOSS organized vertically by mineral group. Clicking on a mineral plate image will bring you to the corresponding MIROFOSS article. Please note this page may take a while to load on slower computers or with slower internet connections.

In crystallography, the triclinic (or anorthic) crystal system is one of the six crystal systems. A crystal system is described by three basis vectors. In the triclinic system, the crystal is described by vectors of unequal length, as in the orthorhombic system. In addition, no vector is at right angles (90°) orthogonal to another. The triclinic lattice is the least symmetric of the 14 three-dimensional Bravais lattices. It has (itself) the minimum symmetry all lattices have: points of inversion at each lattice point and at 7 more points for each lattice point: at the midpoints of the edges and the faces, and at the center points. It is the only lattice type that itself has no mirror planes.
