Inclusions of the extremely rare germanium mineral carboirite in a matrix of sphalerite. From analysed material of the BRGM Workings at an altitude of 2000m (Carboire, Ariege, Midi-Pyrénées, France). Germanium minerals are extremely rare in Nature, since only 32 species from more than 5400 known mineral species are Germanium minerals. Mineral

Carbonatecyanotrichite Locality: Qinglong (Dachang) Sb-Au deposit, Qinglong County, Qianxi'nan Autonomous Prefecture, Guizhou Province, China (Locality at mindat.org) Size: 12.9 x 7.9 x 4.9 cm. Shimmering, powder-blue to sky-blue tufts of soft, felt-like, hairs of carbonatecyranotrichite richly cover all sides of the sculptural, cabinet, calcite-covered limestone matrix of this very beautiful specimen from recent finds in China. Carbonatecyanotrichite is a secondary copper mineral found sparsely in the oxidation zones of copper-bearing ore bodies. Very highly representative and rich for the species and locality. Mineral

Caresite Field of View 1.3 mm; View window 1.3 x 1.0 mm. Thanks to Tony Steede. MOB coll. This particular variety looks similar to some cordylite-(Ce) (or lukechangite) but it is caresite-3T from an analyzed find. William Henderson describes (larger) caresite-3T of apparently similar habits found in May 2002 (Micronews 37 #1 p. 4.) The pale pinkish stuff is altered rhodochrosite. Mineral

Carletonite Locality: Poudrette quarry (Demix quarry; Uni-Mix quarry; Desourdy quarry), Mont Saint-Hilaire, Rouville RCM, Montérégie, Québec, Canada (Locality at mindat.org) A very large example for this form of carletonite, which, due to its size has also acquired an opacity not common to the others here. It is a bit rough-looking and is missing one corner at the bottom. The demarcation between blue and white is so sharp and distinct. 1.6 x 1.6 x 0.9 cm .

Back-scattered electron scanning electron microscopy image of a polished section of the garpenbergite (Grp) type specimen, with carlfrancisite (Cfc), jacobsite (Jcb), alleghanyite (Alh), dolomite (Dol) and kutnohorite (Kut). The arrow points to one area (white) containing a fine intergrowth of stibarsen and paradocrasite. Sample GEO-NRM #20200040.
