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 MONOCLINIC 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 monoclinic crystal system is one of the six crystal systems. A crystal system is described by three vectors. In the monoclinic system, the crystal is described by vectors of unequal lengths, as in the orthorhombic system. They form a rectangular prism with a parallelogram as its base. Hence two vectors are perpendicular (meet at right angles), while the third vector meets the other two at an angle other than 90°.
