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.
Chemical Composition
Mineral species by chemical elements selectable from a
periodic table or search form.
Three options are provided: 1) Sorted by %, 2) Sorted by mineral name or 3) New
Custom weight percent element search.

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.

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