Named after the type locality at the Cap Garonne mine in Var, France. Additional localities for Capgaronneite include in the Broken Hill mine in New South Wales, Australia, at Chanarcillo near Copiapo in Atacama, Chile, at the Frischer Mut Mine in Rhineland-Palatinate in Germany, at Adolf mine in Borsod-Abauj-Zemplen Co. in Hungary, and at Cerro Minado in Andalusia, Spain. Capgaronneits forms likely as an oxidation product of mercury and silver rich tennantite that has been exposed to seawater.

Named for the type locality at the Beatriz mine near the town of Caracoles in the Antofagasta region of Chile. Caracolite is a rare mineral that can be found in additional Chilean localities including the Generosa, Herminia, La Compania, and San Francisco mines in Antofagasta and the Buena Esperanza and Lolon mines in the Tarapaca region, as well as in Germany at the Auguste-Victoria mine in North Rhine-Westphalia, and in Ukraine. Caracolite occurs in oxidized chlorine-rich lead deposits as a secondary mineral. Caracolite will decompose in water and leave behind lead sulfate, PbSO4.

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.

Named for Steve and Janet Cares from Massachusetts, USA, who were the ones to discover the mineral. Late stage hydrothermal mineral from the co-type, and only localities at the Poudrette quarry at Mont Saint-Hilaire near Monteregie and at the Corporation quarry in Montreal, Quebec, Canada. Forms as tabular o pyramidal crystals, sometimes barrel-shaped.

Carleton University in Ottawa, Canada is the namesake of the mineral Carletonite as it is the site where the mineral was first studied. Carletonite is a rare mineral that can be found at its type, and only, locality at the Poudrette quarry at Mont Saint-Hilaire in Quebec, Canada. There, it occurs “in cores of thermally metamorphosed wall-rock xenoliths of shale and interbedded limestone, now hornfels and siliceous marble, in nepheline syenite in a intrusive alkalic gabbro-syenite complex.”
