Chalcophanite is a hydrated zinc manganese oxide. Moore (1875) named chalcophanite by combing Greek roots chalcos and phaneros, for bronze and to appear respectively, as the color of the mineral changes on heating.
Chalcophanite here forms crystals to 1.5 mm. The chalcophanite lines a cavity lines in gossan matrix; larger, later transparent adamite crystals are present, but are difficult to distinguish due to the high luster of chalcophanite. From the collection of E.R. Laskowski (1949-2020), a mining engineer who retired to Tucson, Arizona.
