The University of Geneva maintains this metasite for mineralogy databases. Twelve databases are found at Athena: Mineralogy and are broken into the following topics: alphabetical list, systematic list, elements, sulfides, halides, oxides, carbonates, sulfates, phosphates, silicates, organic minerals, and varieties, synonyms, etc. The site is rounded out with a mineral search and mineral pictures (Frames). The databases are complete with rare and common minerals, which makes this a must-visit for anyone interested in mineralogy.
