The Mineralogy Database was last updated on 9/5/2012 and it contains 4,714 individual mineral species descriptions with links and a comprehensive image library. Visit the "What's New" section for details.  

Each mineral has a page linked to tables devoted to crystallography, crystal structures, X-Ray powder diffraction, chemical composition, physical and optical properties, Dana's New classification, Strunz classification, mineral specimen images, and alphabetical listings of mineral species. There also are extensive links to other external sources of mineral data and information.

What is a Mineral ?
Selected mineral definitions spanning the last century defining the mineral kingdom as matter other than that of the plant or animal kingdom.

Crystallography
This section contains tutorials on the 36 crystal classes. Along with this information are links to tables of each class with all the minerals in that class. Printer-ready PDF files of paper crystal models (assembly required) of the crystal classes can be found here.
3D Crystal models of minerals use JAVA applets from KrystalShaper that can be viewed in a browser window. The rotating form on your left is an actual java applet and not an animated GIF image. If  the model is not visible then install JAVA on your PC.

Crystal Structures
Mineral species and other structures with crystal structure data using the jPOWD applet. The jmol version is located here.

X-Ray Powder Diffraction
Mineral species searchable by D1, D2, and D3 diffraction spacing.

New Dana Classification
Mineral species by New Dana system.

Strunz Classification
Mineral species by new Nickel-Strunz system (courtesy of Jim Ferraiolo).

Determinative Mineralogy
Mineral species by physical and optical properties and by calculated radioactivity.

Alphabetical Listing
Mineral species listings. The listings include synonyms, quick links to pronunciation, images, and java crystal forms, name origin, and chemical formula.

Factoid #15

Aluminum metal was so hard to refine from it's ores that Emperor Napoleon III of France reserved the use of aluminum cutlery for state banquets; thereby, relegating gold and silver forks and spoons to his lesser guests.

The invention of the Hall-Héroult process (1886) of electrolytic decomposition to elemental aluminum effectively replaced the expensive Wöhler process. This eliminated the metal as a rare commodity.

On December 6, 1884 the largest aluminum casting in the world (at that time) was affixed to the apex of the Washington Monument in Washington DC
