My Mineral Collection, Copper Minerals Page

This is my copper minerals collection. This is a big page as there are lots of copper minerals and different habits for many of them - besides, the colors are gorgeous!
Copper Minerals on Other Pages
For native copper, see my elements page. Arsentsumebite, bournonite, diaboleite, duftite, fornacite, kobellite, lengenbachite, linarite, meneghinite, and osarizawaite are on my lead minerals page because the lead content is higher. Aurichalcite, glaucocerinite, and zincrosasite are on my zinc minerals page for the same reason. More (aluminum) than copper puts ceruleite, coeruleolactite, nevadaite and (iron) chalcosiderite on my systematic phosphates page. More (nickel) than copper puts carrboydite, (manganese) nakauriite, and (iron) pisanite, on my systematic sulfates page. Likewise, since there's less copper than other metal(s), aikinite, carrollite, chalcostibite, cubanite, freibergite, polybasite, stromeyerite, valleriite, and wittichenite are on my systematic sulfides page. For turquoise see my gemstones page. I have four of the other five members of the turquoise family: chalcosiderite, coeruleolactite, faustite, and planerite. I don't yet have aheylite.

Thanks to Eric Greene's (Treasure Mountain Mining) auction on eBay for the specimen!	Chrysocolla Chrysocolla is a hydrated copper aluminum hydroxysilicate, used as a copper ore when sufficiently available. The color varies on this Arizona one from blue-green to green at the edges and high points. This one's hard enough to be chrysocolla-impregnated quartz (as is often the case), and named "gem silica" in the jewelry trade.
Row 19
Chrysocolla Three pieces of Arizona chrysocolla - this is the softer non-silicified variety. Thanks to Paul Cordalis' auction on eBay for the specimens!

Connellite Connellite's a complex copper hydroxylchlorosulfate that forms tiny acicular crystals, as on this miniature with tenorite and chrysocolla on a coarsely crystalline cuprite matrix from Bisbee, Cochise County, Arizona. It forms an incomplete series with buttgenbachite, its (hydroxychloro)nitrate analog. Thanks to David H. Garske's (MINERALS and MORE) auction on eBay for the specimen!	Copper Ores This is a large cabinet specimen of mixed copper ores from Morenci, Arizona - the large photo shows that there's azurite, malachite, chalcotrichite, crysocolla, turquoise, and probably a lot more minerals here. This one's really fun to look at under a microscope!
Row 25
Copper Ores As with my other mixed copper ore specimens, it's hard to pick the predominant ore here.	Copper Ores Azurite and malachite (at least), probably from Arizona.

Thanks to Chris Korpi at Pangaea Minerals for the specimen!	Cyanotrichite This cyanotrichite's also from the Grandview Mine - it's the classic location. This one is absolutely exquisite under a microscope - the green clusters are brochantite and there's some darker blue azurite microballs as well. Thanks to C. Carter Rich's table at the 2000 Carnegie Gem & Mineral Show for the specimen!	Cyanotrichite Gorgeous tufts of bright blue cyanotrichite from the 2002 find at the Qinlong Mine, Guizhou Province, China.

Thanks to Gary Lozonne at Lozonne's Minerals for the specimen!
Row 37
Dioptase A beautiful (though uniformly translucent), classic rhombohedral-terminated dioptase crystal perched on a matrix along with some bright apple-green duftite from Tsumeb, Africa.

Enargite on Pyrite Shiny black enargite (a copper arsenic sulfosalt) on pyrite from the Huanzalá Mine, Dos de Mayo Province, Huánuco, Peru. Enargite from some locales (Agua Rica, Catamarca Province, Argentina - similar in mineralization to the famous Butte, Montana site) can have 1) significant lead substituting for the arsenic and 2) a tin-vanadium mix also substituting for the arsenic - approaching colusite in composition. It's a dimorph with luzonite. Thanks to Alan & Marsha Day at Mineral Exploration Services for the specimen!	Euchroite Euchroite's a hydrated copper hydroxyarsenate - this beautiful small thumbnail of pure euchroite is from the type locality of Lubietová (Libethen), Stredoslovenský Kraj, Slovak Republic. Thanks to Tom & Vicki Loomis at Dakota Matrix Minerals for the specimen and the image!	Famatinite A miniature of pinkish-gray famatinite in an enargite and tennantite matrix from Flathead County, Montana. Ex: Continental Minerals, 1970s. Thanks to Tony Nikischer at the Excalibur Mineral Company for the specimen!
Row 40
Glaukosphaerite Glaukosphaerite's a copper nickel hydroxycarbonate and a member of the rosasite group (the nickel analog of rosasite). This miniature is from the KM3 Mine at Lavrion, Greece. Thanks to Lars Jorgensen at Geosystems for the specimen!	Juangodoyite An excellent micromount of bright blue juangodoyite (an anhydrous copper sodium carbonate) on matrix from the type locality of the Santa Rosa Mine, Tarapaca Province, Chile. It has a Simkev Micromounts tag. Juangodoyite's a new mineral - the name was approved in 2004. Thanks to Michael Swanson's auction on eBay for the specimen and the image!	Khaidarkanite A very rare small thumbnail of bright sky-blue tufts of khaidarkanite (a hydrated copper aluminum sodium hydroxyfluoride) on matrix from the type locality of Khaidarkan, Fergana Valley, Osh, Krygyzstan. Thanks to Tom & Vicki Loomis at Dakota Matrix Minerals for the specimen and the image!
Row 41
Kinoite This kinoite, a copper calcium hydroxysilicate, (as does most specimen-grade kinoite) comes from the Christmas Mine in Gila County, Arizona. Most of the kinoite from there (this one included) is covered with tiny colorless pinacoidally-terminated apophyllite crystals. Thanks to Gary Lozonne at Lozonne's Minerals for the specimen and the image!	Kinoite Kinoite (again from the Christmas Mine) - this time more widely disseminated and without much covering apophyllite. Thanks to Mike Keim at Marin Minerals for the specimen!	Kolwezite A cute thumbnail of (almost type-locality) grayish-green kolwezite (copper cobalt carbonate) from Mashamba West Mine, Kolwezi, Shaba, Congo. Thanks to John Sobolewski's auction on eBay for the specimen!
Row 42
Krohnkite Krohnkite (kroehnite, kröhnite) is a hydrated copper sodium sulfate - this miniature of granular and massive krohnite comes from the type locality of Chuquicamata, Calama, Antofagasta Province, Chile. Thanks to Anthony Jones' auction on eBay for the specimen!	Krutaite A micromount of metallic krutaite crystals on matrix from the El Dragón mine, Quijarro Province, PotosÍ Department, Bolivia. It forms a series with trogtalite where cobalt replaces the copper. Thanks to Val Collins' auction on eBay for the specimen!	Ktenasite A small cabinet specimen of ktenasite (a hydrated copper zinc hydroxysulfate) on matrix from the mid-1970s find on the 31 stope at the 79 Mine, Hayden, Gila County, Arizona. Thanks to Tony Nikischer at the Excalibur Mineral Company for the specimen!
Row 43
Lammerite A miniature of forest-green lammerite (a copper phosphatoarsenate) and a little bit of (probable) blue lemanskiite (larger image, center) on matrix from the Abundancia Mine in Guanaco, Taltal, Antofagasta, Chile. Thanks to the House of Onyx for the specimen!	Lammerite A large thumbnail of lammerite with blue lavendulan from the El Guanaco Mine, Guanaco, Antofagasta, Chile. Thanks to Anthony Jones' auction on eBay for the specimen!	Langite Langite's a "hydrated brochantite", copper hydroxysulfate with two molecules of water - it's also dimorphous with wroewolfeite. The closeup shows possible rare langite crystals on this small cabinet specimen from Richtárová, Spania Dolina, Czechoslovakia. Thanks to Emilie & Ron Kendig's auction on eBay for the specimen and image!
Row 44
Lavendulan This micro of lavendulan, a rare hydrated copper sodium calcium chloroarsenate, comes from the El Guanaco Mine, Guanaco, Antafogasta Province, Chile. It's the chloroarsenate analog of sampleite, a dimorph of lemanskiite, and forms an incomplete series with zdenekite, where lead replaces the calcium. Thanks to Tom & Vicki Loomis at Dakota Matrix Minerals for the specimen!	Lemanskiite This is a very nice miniature of a newly-approved (2001) mineral, lemanskiite (a hydrated copper calcium sodium chloroarsenate), with malachite on matrix from the type locality of the El Guanaco Mine, Taltal, Antofagasta, Chile. It's a dimorph of lavendulan. The green mineral accompanying it is probably lammerite. The label is signed by Chet Lemanski! Thanks to the House of Onyx for the specimen!
