Member of:Svabite Subgroup > Apatite Supergroup
Name:Named after Anton Svab (1703-1768), Swedish mining official.


Apatite Supergroup. Svabite Subgroup. The arsenate analogue of fluorapatite.

Forms a series toward fluorapatite with an increase of P for As. Also forms a series toward hedyphane and mimetite with an increase of Pb and Cl.
