(Zn,Cu)5(CO3)2(OH)6
Orthorhombic
Aurichalcite, a zinc copper carbonate hydroxide mineral, was reported from Franklin and Sterling Hill by Palache (1935), but is largely unstudied. It is less common than azurite or malachite, although hand-sized specimens have been preserved. No data have been published. Aurichalcite occurs as tufts and clusters of very light blue, acicular crystals, commonly on a severely altered goethite-bearing matrix at both deposits.
The occurrences are probably the same as for azurite and malachite, but may represent a later stage of oxidation. Jenkins (1992) reported an occurrence of aurichalcite associated with orthoserpierite in the Sterling Mine, and Jenkins and Misiur (1994) reported an occurrence with oxidized sulfides.
