Aurichalcite |
| 2(Zn,Cu)CO3.3(Zn,Cu)(OH)2 |
| Orthorhombic? |
Aurichalcite forms rosettes in a friable limestone and a thin coating of acicular crystals on limestone. Its color is pale bluish green. It has been found, associated with limonite and malachite, in numerous specimens from Franklin, apparently parts of an originally single mass, with what appear to be remains of franklinite crystals. There is in the Hancock collection a single specimen of the mineral from Sterling Hill, showing rosettes on limestone with black dendrites of manganese dioxide.
