ID: CC21877
A rusty brown gossan matrix of vuggy and porous heavily iron-stained Quartz veinstone has its top surface richly invested with dark emerald green rosettes of crystallised Chalcosiderite, a copper-iron phosphate. The specimen is from the Phoenix United mine at Minions, close to Liskeard in Cornwall, England, the type locality for Chalcosiderite. Hundreds of rosettes to about 1 mm diameter are spread out over the matrix. Similar olive-green rosettes also cover one patch, likely to be Chalcosiderite of a slightly differing composition or another phosphate mineral. Similar sized apricot-coloured spheres nestle in a shallow cavity to one side of possible Goethite.
