Azoproite is a rare manganese iron borate mineral with the chemical formula (Mg,Fe{{sup|2+}}){{sub|2}}(Fe{{sup|3+}},Ti,Mg)(BO{{sub|3}})O{{sub|2}}. It was first identified near Lake Baikal, Russia. It was named after the Association pour l'Etude Géologique des Zones Profondes de l'Ecorce Terrestre, whose acronym is AZOPRO in French.[https://mindat.org/min-442.html Azoproite] {{Webarchive|url=https://web.archive.org/web/20161201174200/http://www.mindat.org/min-442.html |date=2016-12-01 }} on mindat.org
