This site is designed to determine the type of mineral or minerals in a rock sample. It contains the most common (and a few rare and interesting) minerals found throughout the world today, but does not contain all the known minerals. Links to other websites provide detailed information about, and photographs of, the selected minerals.
To use this program, you need to visually examine your mineral sample, do a few simple tests and input your results on the search table. The program will search the database and return brief descriptions of those minerals similar to your input. Ideally, there will be 2 to 3 minerals meeting your criteria and you can click on the mineral name to go to other on-line resources which have more detailed descriptions.
In creating this site, I've avoided linking directly to just a photograph, but have instead linked to pages where mineral photographs and descriptions are available. If you wander off looking at the other sites and discover new and exciting things about minerals, all the better. I hope you enjoy this program and would like to hear from you regarding its usefulness.
