Aurichalcite


Aurichalcite is a zinc copper carbonate. The mineral name derives from the Latin aurum for gold and Greek chalcos for copper, together meaning "golden copper" or brass, since aurichalcite affords brass when smelted. While known since the 17th century, it was Boettger (1839) who assigned the species its modern name.

Aurichalcite here forms bladed crystals to 2 mm with a rich blue-green color. They forms a thick continuous coverage on gossan matrix. Minor associated hemimorphite is typical of this material from the 79 mine, which came out in the 1970s. This specimen was part of the Charles Trantham (1936-2020) estate.
