Strunz Groupings

From Mindat

Strunz groupings are a means of classifying minerals by the anion groups that they contain (these are groups such as sulfates, carbonates, phosphates, sulfides, etc.) The listing by Strunz groups (http://www.mindat.org/strunz.php) allows one to drill down to the subgroups and see which minerals are closely related to them. You can also see the minerals in a Strunz group (subgroup) on the mineral display page. They are also accessible in the "Search" button from the navigation header. The Strunz groups are named for Hugo Strunz who authored the 1941 book "Mineralogische Tabellen" (there is an 9th edition in English that was published in 2001).
