A comprehensive list of minerals with Wikipedia articles, organized by alphabetical order. Each mineral entry includes its chemical and physical properties, crystal structure, and variety names.
A crystal is a solid material with a highly ordered microscopic structure, formed by atoms, molecules, or ions arranged in a crystal lattice. Learn about the different types, symmetries, and shapes of crystals, and how they are studied by crystallography.
This web page provides a comprehensive list of minerals that have been approved, grandfathered, or discredited by the IMA, the international scientific group that recognizes new minerals and names. The list is divided into alphabetical groups and includes various abbreviations and codes for different mineral properties and statuses.
Danburite is a calcium boron silicate mineral with a hardness of 7 to 7.5 and a specific gravity of 3.0. It is usually colourless, yellowish, or brownish and occurs in contact metamorphic rocks. It is named for Danbury, Connecticut, where it was first discovered in 1839.
Dolomite is a carbonate mineral composed of calcium and magnesium ions, with the formula CaMg (CO 3) 2. It forms white, tan, gray, or pink crystals and is related to huntite and ankerite. Learn about its history, formation, and uses.
Serpentine subgroup are greenish, brownish, or spotted minerals formed by the metamorphism of ultramafic rocks. They have various uses, such as magnesium source, asbestos, and decorative stone, and include antigorite, lizardite and chrysotile polymorphs.
Cristobalite is a high-temperature polymorph of silica with the same formula as quartz, but a different crystal structure. It has a cubic and a tetragonal form, and is metastable below 1470 °C.
Apatite is a group of phosphate minerals, usually hydroxyapatite, fluorapatite and chlorapatite, with high concentrations of OH-, F- and Cl- ion, respectively, in the crystal. Chlorapatite is a rare form of apatite that contains chlorine and is used as a source of phosphate and uranium.
