Stibiconite, also formerly known as stibliteRobert Philips Greg, William Garrow Lettsom (1858). Manual of the Mineralogy of Great Britain & Ireland. — London: John Van Voorst, 1858.{{rp|372}} or antimony ochreBulletin of the United States National Museum. Published under the Direction of the Smithsonian Institution. Washington: Government Printing Office, No.32, 1887.{{rp|118}} is an antimony oxide mineral with formula: Sb₃O₆(OH). Its name originates from Greek {{transl|grc|stíbi}} ({{lang|grc|στίβι}}), 'antimony' and {{transl|grc|kónis}} ({{wikt-lang|grc|κόνις}}), 'powder', alluding to its composition and habit. It is a member of the pyrochlore super group.
