Carbonatecyanotrichite
Named as the carbonate-dominant analogue of cyanotrichite. Carbonatecyanotrichite is an uncommon mineral that forms as a secondary mineral in oxidized copper-bearing deposits in localities in Kazakhstan, Kyrgyzstan, the United States, Canada, France, Switzerland, England, Wales, New Zealand, and a few others. It is found in association with volborthite, malachite, azurite, aurichalcite, pseudomalachite, spangolite, gibbsite, allophone, tangeite, brochantite, and langite.
