Stibiconite is an antimony oxide mineral with formula: Sb3O6(OH). Its name originates from Greek (Greek, Ancient (to 1453);: [[wikt:στίμμι|στίβι]]), 'antimony' and, 'powder', alluding to its composition and habit.[2] [3] It is a member of the pyrochlore super group.
It was first described in 1862 for an occurrence in the Brandholz – Goldkronach District, Fichtel Mountains, Bavaria, Germany.
It occurs as a secondary alteration product of other hydrothermal antimony minerals such as stibnite. It occurs in association with cervantite, valentinite, kermesite, native antimony and stibnite.[3]
