Waylandite

Bismuth-containing mineral

Waylandite is the phosphate analogue of arsenowaylandite and the aluminum analogue of zaïrite. The mineral was approved by the IMA in 1962, and was published the same year. Waylandite was named in honor of Edgar James Wayland. It is a member of the alunite supergroup, and a member of the plumbogummite – also known as crandallite – group. So far, only two bismuth-bearing members of the alunite supergroup are known, one of which is waylandite, alongside its ferric iron analogue zaïrite.
