The American Mineralogist Crystal Structure Database website, maintained by the Mineralogical Society of America and the Mineralogical Association of Canada and sponsored by the National Science Foundation, "includes every structure published in the American Mineralogist, The Canadian Mineralogist, and the European Journal of Mineralogy." The authors are also currently adding data from Physics and...

The California Institute of Technology created this website to provide valuable information about the color in minerals and data on mineral absorption spectra and Raman spectra. The modest site features additional information on silica polymorphs, desert varnish, ametrine, and manganese dendrite. Students can discover the technology used to collect the spectra data including the diode-array...

The Database of Zeolite Structures is provided by the Structure Commission of the International Zeolite Association. Links include an Atlas of Zeolite Framework Types, Collection of Simulated XRD Powder Patterns for Zeolites, Catalog of Disordered Zeolite Structures, Schemes for Building Zeolite Framework Models, and Zeolite Structure References, as well as various publications. The database can...

This Louisiana State University website features its research of the mineral tourmaline, which can provide "information on the thermal and fluid history of rocks in which it develops, is intimately associated with some of the world's premier metallic ore deposits, retains chemical signatures of the sources of tourmaline detritus in clastic rocks", and has many additional valuable petrogenetic...

Mindat.org is described as one of the largest mineral database on the Internet with holdings that include over 11,000 minerals and information on over 100,000 mineral occurrences worldwide from over 23,000 sites. Visitors can search the archive using a mineral name or locality, and can browse common search topics or the newest entries. Once found, the pages contain a wealth of information about...

John A. Jaszczak at Michigan Technological University presents the characteristics of graphite at this website. Students can find concise descriptions and helpful images about graphite properties, spirals, and structures. The website offers images and descriptions of graphite found all over the world. Using Macromedia Flash Player, students can observe graphite levitating due to its diamagnetic...

Dr. Phillip Barak, Associate Professor of Soil Science at the University of Wisconsin-Madison, has put together this "web-based focal point and resource for 3-D visualizations of molecules and minerals." A collection of 3-D, interactive models of molecules and minerals, these detailed, color images and animations are designed for instructors and students alike. Visualizations include soil organic...
