This tool allows you to search or calculate molecular weights, generate empirical formulae and perform compositional analysis on ANY chemical formulae of interest. The Composition tool has four functions which are Search weight, Calculate weight, Empirical formula and Get composition; that perform as their namesake specifies. See the images below on what it can do.
This tool allows you to identify minerals based on their visible qualities or measurements. The tool is a property search or comparison engine that focuses on the physical aspects of minerals. These properties are: color, streak, luster, diaphaneity, fractures, tenacity, cleavage, parting, density, specific gravity and hardness (both Mohs and Vickers scales). See the images below on what it can do.
This tool can perform custom data searches on the various properties observed when a mineral is exposed to polarized light. These properties require advanced knowledge in mineral optics and are obtained via specialized optical equipment. The supported properties are Optic classes, Optic signs, Refractive indices, 2V Angles, Dispersion and Birefringence. See below for examples.
Another measurement-oriented tool and very accurate provided you know the various crystallographic properties your mineral possesses. This tool can search for common crystallographic constants, provided you can obtain them from your mineral. The properties supported are Crystal Systems, Crystal classes, Hermann-Mauguin symbols, Space groups, Cell dimensions, Cell angles, Cell volume and Cell density.
A tool for searching, sorting and analyzing Dana and Strunz mineral classification IDs. The tools can accept a valid Dana or Strunz ID and uses it to search for a mineral that matches it, or break down individual components of the ID according to its classification scheme. It also allows you to search minerals by their supergroups, example; if you want to know all silicate minerals is the database, this is the tool to use.
